When it comes to a real life situation, with a woman "getting all up on it", it would take inhuman willpower to inhibit any sexual response, especially when they are turned on.
The main point about these studies is that there was no voluntary inhibition (as tested with brain scans to see brain activation) when males were shown bonobo sex, heterosexual sex when they were gay, gay sex when they were hetero, ie the men had sexual responses to the very same stimuli they said they were excited by. It was not a case of the men stopping themselves having erections when looking at bonobos having sex. Neither their bodies nor their minds were turned on and the brain scans showed that this was not due to intentional inhibition of a response.
For women though, there was a genital arousal response to anything that involved sex even though they were not turned on mentally.
When there was no reason for the men to inhibit their sexual response and brains scans confirmed no inhibition going on they still only responded to what they said turned them on. Women responded to everything in the genitals while to only certain things in the head.
sprite wrote:It presents the possiblity for females that they can learn to have all kinds of sex. If they have the genital arousal in any sexual situation then all that is needed is for them to be taught to want the sex mentally and they can then be 'willingly' having sex of any description. Perhaps this is why women more easily than men can learn to enjoy sex with other women or pretty much any kind of sexual behaviour the porn industry might want from them.
It suggests that for men who do not have the genital arousal in connection to any kind of sex that a straight male will not be able to learn to enjoy sex with another male. He does not have the automatic sexual arousal to any sex.
Should be pointed out here, though, that these differences between men and women are not absolute and ony significant differences. As with everything there is variation and overlap.
sprite wrote:Mr.Samsa wrote:I'm not aware of rape fantasies in history, but I could be wrong. Do you know of any evidence for them?
Well, women have not left much art or literature etc themselves.
There was that novel Clarissa from 1767 where the main character Lovelace drugs and rapes her. I saw something about this the other week and can't remember where just now, but it was basically that female readers of the book 'fell in love' with and wanted Lovelace themselves.

There are a number of them, including the primacy of the ipod (being released first), the "catchy" marketing (salient in society), the novelty factor (the clickwheel), and a larger range of functions which the Zune took to long to replicate. All added up, we can easily account for the preference without an appeal to evolution.
But women's sexual fantasies are/were secret to themselves. They are not something public or fashionable or even known to exist in anyone else at least initially.
It is the inner conflict over these for women. Some feminists gave up thinking about this because it was too difficult to deal with. There continues this great problem for many women regarding 'sex' whether about these type of fantasies or porn, sex work etc etc.
sprite wrote:These are things which can be used against women to argue that women lie about rape or are all very happy to be sex workers etc etc.
Appeals to evolution are even used to show that females are actually very promiscuous or want to be raped as we have seen on this thread.
These are arguments about the 'nature' of women and female sexuality which even use mis-representations of females of other species.
It is essential for women to know the male bias in the representaions of female nature in humans and across species. To have an understanding of the evolution of sex and the sexes, and selection acting on females as well as males etc etc.
sprite wrote:A couple of points.
In the experiments where women had sexual arousal responses to pretty much any depiction of sex one theory (expressed by John Bancroft who does much of the research on human sexual behaviour)is that 'sexual arousal' in females ie vaginal lubrication, is an evolved self-protective mechanism. The theory is that in the presence of sexually aroused males females may be forced to copulate whether they choose to or not. So the female may not want to copulate so she has no conscious sexual arousal but unavoidable copulation may then be injurious due to ack of lubrication. The body has therefore evolved to have the lubrication - the phyiscal readiness - without the actual desire. A kind of protective stress arousal.
I'm not sure but I seem to remember that vaginal lubrication can/does occur in stress situations.
It is something which needs considering. And especially so when lack of lubrication and vaginal injury is required for rape accusations to be taken seriously in the first instance.

That would be interesting.
Faulks begins in the eighteenth century with Samuel Richardson’s Clarissa and the rakish Lovelace. His sole purpose in life is to seduce as many women as possible and endlessly pursues the novels heroine Clarissa. He is determined to have Clarissa at any cost and his unerring self-belief makes him the terrifying epitome of male aristocratic sexuality. Despite raping Clarissa, Lovelace remains resolute in his self-belief and remarkably female readers of the time were obsessed and seduced by his character.

But neither men nor women had been exposed to bonobo sex before and the straight women will have been exposed to lesbian sex more than straight men to gay sex so habituation is not the issue here. And the awkardness of the situation is the same for both sexes.
sprite wrote:Mr.Samsa wrote:I'm not sure what point the "secrecy" of them is? Cultural fads are caused by common environmental factors, whether everyone engaging in them are aware of the popularity of the thing is irrelevant.
I would agree that what goes on in the head re. specific sexual fantasies have got there from images from the environment.
I did say earlier that women's 'rape' fantasies may be due to the environmental portrayal of sex being mainly created by men so women take their images from the expression of male sexual 'wants'.
This is a problem we have re 'what do women want' when women have, and have had, such a minor public presence. Women are reactive to expressions by men rather than being initiators of what occurs in public.
And that's why some of us look to wider nature for some clues of what women might themselves be - Hrdy's'The Woman That Never Evolved' for example.
No doubt you would argue that this is irrelevant to the here and now but personally I'm sick of hearing about the great mystery that is the human female. I absolutely believe that as well as looking at the male-created world we live in and and in which women react, that the evolutionary biology of sex and the sexes provides some essential basics. If we do not understand those basics then we simply continue to flounder around and women continue to be susceptible to sexual manipulation.
sprite wrote:Mr.Samsa wrote:I'm not sure what you mean by "male bias in the representation of female nature"?
Perhaps my previous point gives you a clue?
Or to take Darwin as an example - the coy (rather than discriminating) female etc. But then Darwin also came up with 'female choice' as one side of sexual selection. It took one hundred years for this to actually even start to be accepted.
And then suddenly with feminism and 'sexual liberation' and 'sexual freedom' female animals are 'discovered' to be mating with far more males than they 'ought' according to the science.
Then we get thrown over to the polar opposite - women are actually at least as promiscuous as men. It all fits with the current thinking about the sexes being the same and that monogamy is unnatural and enforced by religion etc etc. Men can get loads more sex with loads more women, sexual rejection by females of males isn't 'natural', rape isn't real, women love to be in sex work, men don't 'naturally' want to stay around with one woman and raise kids together. Women don't want this either.
But hold on. Evolutionary biology and what happens in other species never showed evidence for this.
One version gives us the 'madonna' and the other version the 'whore' ie the two unreal female natures that men want depending on whether they want a wife or casual sex.
I believe there are some basics about sex which need to be understood.
And I believe that knowing as much as possible about the evolution of sex and the sexes is the best protection against manipulative use of cherry-picked or even false evidence.

sprite wrote:It is actually difficult to tackle this with someone who only considers the here and now relevant, but I'll give it a go.
I want to go right back to anisogamy. I don't know how much you know about this but basically once upon a time ()sex cells were of one size. Selection led to sex cells of two distinct types (I can discuss this in much more detail if you wish). At about the same time multi-celled animals evolved. These first animals were hermaphrodites (I can go in to the reasons this is most likely so if you wish) so bodies of one type produced the two types of sex cell ie not yet male and female bodies.
Selection led to two sexes which now experienced different selection pressures depending on whether they produced eggs or sperm.
While sharing more or less the same genome mechanisms evolved to alter development depending on whether the body was producing one sex cell or the other.
So we get sexual dimorphism.
If sexuality is the same for both sexes then how could sexual dimorphism evolve?
sprite wrote:*snip*
So your question 'What difference between male and female sexuality?' if you just mean humans implies that you think that humans are either monogamous and so have little difference like gibbons, which evidence very much goes against, or you think that humans have evolved something unique which means they can have different selection pressures on males and females but these do not affect their bodies and behaviours - any difference is about something else.
So you are suggesting that while in other species differential reproductive success within each sex is different and results from differences in bodies and behaviours and leads to the spreading of certain different traits in each of the sexes, in humans differential reproductive success has done nothing.
Or do you think differential reproductive success in other species also does nothing which is inherited?

From things you have said elsewhere I'm presuming that this is basically about pleasure/pain doing the teaching?
So if we see a difference in pleasure and pain between the sexes what would that tell us?

Firstly back to hermaphrodites. In most, though not all, simultaneous hermaphrodites each one tries to avoid being inseminated while trying to inseminate the other. Is there some pleasure connected to insemination and pain connected to being inseminated? Why would that be? In some cases there is in fact genuine pain - being stabbed and the seminal fluid burning through the skin, for example. But even in the case of fish where the gametes are simply being released there is still this difference. It would appear to be painful to release eggs but not sperm? So we get 'sperm' trading where the most keen to mate releases eggs first - does the more painful thing? - and then the exchange commences.
Why have they evolved to experience different pleasure or pain in relation to eggs and sperm do you think?
In the few hermaphrodites where it seems to be preferable to receive the sperm it appears to be because the sperm is digested ie used as food rather than to fertilize eggs. Far less painful when sperm is a useful food source. (Then we get males evolving chemicals in the ejaculate or the 'love darts' of snails which stop their sperm being digested by the mate).

There was a fascinating tv documentary recently about a community of chimpanzees that has become isolated in a steep narrow valley. The land around them was bare and dangerous to venture in to. One female had reached puberty and kept going to the edge and looking across the bare land. She actually did set off to find a new community but returned a few days later having obviously failed to cross the bare land even though it was only a few miles to forest and other chimpanzees.
So the males, presumably, feel pleasure in remaining in their birth group but the females when they reach puberty feel pain and seek pleasure elsewhere?

It's impossible to tell from such an example, as the females would have vastly different learning experiences from the males..
Mr.Samsa wrote:This doesn't seem relevant to my original point though, which was that even fundamental biological needs are not simply a function of evolution. As a very simple example, even though eating and hunger is most likely an evolved trait, we still eat even when we aren't hungry - like when we go out on dates, or to cheer ourselves up, or at birthday parties, etc. The point is that sometimes we do topographically identical behaviors for vastly different reasons, and if we tried to attribute the "cheering up eating" to an evolutionary process, then we'd be flat out wrong. The same applies to thing like sex - given the correct learning environment, a person with a "low sex drive gene" (for simplicity's sake) could become the most lascivious horn dog, and equally someone with the "aggressive sex gene" could become someone who isn't turned on by anything but very gentle, sweet lovemaking.
In other words, we do these behaviors for a number of vastly different reasons, and to treat them all as a singular group is a mistake.

Some women do, some women don't. But that's not really the question, because even if we could demonstrate that biologically men and women have the same default setting for sex, we would still expect men to find it more pleasurable than women in our current society. So the fact that we find this doesn't tell us anything about our evolutionary past as it is predicted by two separate theories.
Mr.Samsa wrote:I'm confused by your last line: do you really think men believe that "any sex is better than none"? Part of the reason I wanted to differentiate "male bias" from "patriarchal bias" above is precisely this reason - stereotypes exist for both sexes and the patriarchy can be damaging to both. So, this bias might lead to a belief that women should be pure virgins and any girl that ever has sex is a "whore", but it also leads to the hilariously mistaken view that men love sex, that it takes up a lot of their life, and that they'd do almost anything to get it.
I think we do have a problem, but it's probably more to do with the cartoon characters of each sex that our society has created.

This is an odd response. Are you suggesting that if your evolutionary explanation is correct, then it's perfectly reasonable for the man to respond to the women by suggesting she has evolved incorrectly? It's nonsensical.
Mr.Samsa wrote:We're talking about science, the results are descriptive not prescriptive.

Mr.Samsa wrote:sprite wrote:Sex is not about sharing fluids but about a one way journey of sex cells from him to her. Not a minor difference.
Arguably true, but discussing the evidence surrounding how this affects behavior is the problematic part. This is the key part of the disagreement. I accept sexual selection occurs, and I accept that it's probably occurred in humans (I see no reason to doubt it). However, this doesn't not mean that we can automatically attribute any differences between men and women to sexual selection, and just because a behavior is sexual does not validate that leap in logic at all.

Well, female sexual interest varies due to the menstrual cycle with a peak around ovulation and probably pre-menstrually. I think anyone who has ever been in a heterosexual relationship knows how the relationship varies across the cycle.
See The Evolutionary Biology of Human Female Sexuality which puts in in terms of womens having more than one sexuality but basicaly is about how women think and feel about sex changes across the menstrual cycle.

sprite wrote:I think the basic issue here boils down to what I think is different in humans. Our mating system has been one where more successful reproduction ie more survival of offspring, has come about by both sexes having to largely go against their 'nature' (through a mixture of evolved mate-guarding and evolved cooperation between philopatric males). Whatever genetic changes there have been, and there surely have been some, we are not 'naturally' monogamous but pair-bonding is what produced the best outcome for offspring.
See for example Primeval kinship: how pair-bonding gave birth to human society
Where monogamy exists in other species it is mostly in isolated family groups where it occurs because females stop the male mating with other females and males stop the female mating with other males.
We had to manage our pair-bonding+male parental investment within large multimale-mutifemale groups.
Due to a number of things we inherited from our immediate ancestors (eg male philopatry, sexual dimorphism)females could be mate-guarded more easily than males.
So we have this mis-match in both sexes between the more promiscuous (though still very different between the sexes) nature and the needs of offspring. Both sexes had to compromise between their own inherited attraction to novel members of the other sex and the survival of offspring.
Then we get the greater dominance of some males and so on.
So that is why we struggle so much with our 'wants' and with the demands of offspring and problems in reproductive relationships and control of females etc etc.
Currently females can have direct access to resources or the state can take over paternal investment in offspring or people can even give up the costs of offspring etc etc so both sexes can revert to a more promiscuous sex life.
But even that earlier nature, which will have also been altered for some (as selection has likely selected more pair-bonding propensities in some or in parts of the life-cycle), will be one of differences between the sexes. These differences will be the basic ones connected to the effects of the different gametes on the bodies that produce them plus probably other differences that have evolved during our own evolution since the pan/homo split.

Exactly what it says.
The production of eggs leads to something different re. the experience of peasure/pain than does the production of sperm.
As the meeting of eggs and sperm is reproduction, why there are two sexes, why the two sexes interact etc etc, this interaction means that what is good/pleasurable for the goose is not necessarily good/pleasurable for the gander. Conflict.
sprite wrote:Mr.Samsa wrote:sprite wrote:Secondly a quite different example, chimpanzee (and bonobo) female dispersal.
Males always stay in their birth group, females mostly disperse.
There was a fascinating tv documentary recently about a community of chimpanzees that has become isolated in a steep narrow valley. The land around them was bare and dangerous to venture in to. One female had reached puberty and kept going to the edge and looking across the bare land. She actually did set off to find a new community but returned a few days later having obviously failed to cross the bare land even though it was only a few miles to forest and other chimpanzees.
So the males, presumably, feel pleasure in remaining in their birth group but the females when they reach puberty feel pain and seek pleasure elsewhere? The sexes experience differences in pleasure and pain? Why? Does this not mean that they have some innate difference which means they experience these pleasure/pain differences?
It's impossible to tell from such an example, as the females would have vastly different learning experiences from the males..
Such as?
sprite wrote:Mr.Samsa wrote:This doesn't seem relevant to my original point though, which was that even fundamental biological needs are not simply a function of evolution. As a very simple example, even though eating and hunger is most likely an evolved trait, we still eat even when we aren't hungry - like when we go out on dates, or to cheer ourselves up, or at birthday parties, etc. The point is that sometimes we do topographically identical behaviors for vastly different reasons, and if we tried to attribute the "cheering up eating" to an evolutionary process, then we'd be flat out wrong. The same applies to thing like sex - given the correct learning environment, a person with a "low sex drive gene" (for simplicity's sake) could become the most lascivious horn dog, and equally someone with the "aggressive sex gene" could become someone who isn't turned on by anything but very gentle, sweet lovemaking.
In other words, we do these behaviors for a number of vastly different reasons, and to treat them all as a singular group is a mistake.
So why do we not have cultures where men exchange sex for resources from women?
Or exchange sex for protection from women?
Or exchange sex for protection of their children?

Are you really suggesting that our aversion to rape is because it means that we have no control over our evolutionary futures?
No. A female's aversion to rape is because she evolved from successfully reproducing females who were successful because they could prevent rape.
Behaviours evolve because they lead to more offspring that have those behaviours.
If females that allow males they find unattractive to fertilize their eggs have fewer numbers of offspring than females who have mechanisms that discriminate between males or between sperm then 'female choice' evolves.
Are you saying 'female choice' is not an evolved mechanism?
Geez, one hundred years it took to get past the male bias against female choice and forty years later we are back there again.

I'm sure this is part of the problem regarding sexual rejection for men. Even some have asked this question on these forums, and a gay friend once asked me the same ie why not just enjoy the sex? So we get all kinds of theories from men about how women are teasing them, leading them on, manipulating them, being vengeful etc etc. If men think women really feel the same as they do about sex ie any sex is better than none, then we have a serious problem.
Some women do, some women don't. But that's not really the question, because even if we could demonstrate that biologically men and women have the same default setting for sex, we would still expect men to find it more pleasurable than women in our current society. So the fact that we find this doesn't tell us anything about our evolutionary past as it is predicted by two separate theories.
How could the sexes have evolved the same default setting for sex?
Give examples where this has happened in other species.
Under what envrionmental conditions would such a thing evolve?
Where is this environment in our past?
sprite wrote:Mr.Samsa wrote:I'm confused by your last line: do you really think men believe that "any sex is better than none"? Part of the reason I wanted to differentiate "male bias" from "patriarchal bias" above is precisely this reason - stereotypes exist for both sexes and the patriarchy can be damaging to both. So, this bias might lead to a belief that women should be pure virgins and any girl that ever has sex is a "whore", but it also leads to the hilariously mistaken view that men love sex, that it takes up a lot of their life, and that they'd do almost anything to get it.
I think we do have a problem, but it's probably more to do with the cartoon characters of each sex that our society has created.
I agree that stereotypes are a problem and variation is not given enough attention.
But when I can look at other species and see both these stereotypical behaviours in the males and females, and differences that can be explained by the very same reasoning that explains the stereotypes then I don't see why all this is suddenly irrelevant for humans.

Arguably true, but discussing the evidence surrounding how this affects behavior is the problematic part. This is the key part of the disagreement. I accept sexual selection occurs, and I accept that it's probably occurred in humans (I see no reason to doubt it). However, this doesn't not mean that we can automatically attribute any differences between men and women to sexual selection, and just because a behavior is sexual does not validate that leap in logic at all.

Trying to sum it up, male sexuality is generally persistent behaviour towards females, usually those with the clearest signs of fertility, about 'pick up lines' and tactics - hey, look at porn sites and the adverts for how to get women to f**k.
Compared to females it is a lot less discriminating (though men will be choosy even with sex workers eg in brothels where the women are lined up to be selected from).
It's about being quite choosy when it comes to a mother for children.
It's about novelty of women in terms of arousal. About enormous pleasure from looking at naked/semi-naked women's bodies. (way more than women get looking at men).
It's about getting turned on by noisy female sexual responses (even faked ones).
It is centered in the genitals.
It is orgasm-oriented.
It is massively impressed with semen.
It is not about reading romance novels much, nor overly 'chick flicks'.
It is about conquering or seducing, achievement, 'scoring'. Like getting it is some sort of challenge, like successfully working past obstructions to the goal.

Women are only fertile for a few days, about three I think. They aren't menstruating on the other 25 days of the cycle! Nor when they are pregnant. Nor when they are not fertile decause they are breast-feeding.

Yes, I am saying that our monogamy is largely learned. Though those ancestors who found pair-bonding easier and so had the most successful offspring likely had genetic variations connected to this and there would then be some evolved changes in the human.
For instance there have been changes in human semen in that copulatory plugs may have been lost (they exist in chimpanzees).
There has probably been selection on men for traits that help with bonding with women and especially with children.
I've said from the start that monogamy is not natural.
While traditionally it has been seen as unnatural for men and natural for women more recently the fact that it is natural for neither sex has led to some very confused thinking about female sexuality such as it is the same as male sexuality.
Monogamy is not natural but the non-monogamous nature of the two human sexes is as different as the non-monogamous nature of the two sexes in other species.

But these animals do not learn to behave differently regarding their sex cells - they have been selected to behave differently because they have experienced different selection pressures due to their sex cells.

There are a number of different things, but undeniably males and females across species have different learning experiences.
And why should the females on reaching puberty leave the only community they know to join strangers - and have a very difficult experience while doing so - while the males have absolutely no instinct to do so? During their upbringing the females have avoided the periphery of the group as there is danger from stranger males. But puberty hits and off they go. Something hormonal happens and their dispersal behaviour results.

They occur in the west due to changes brought about by female attempts to regain control over their reproduction - a very natural thing to seek when the environmental conditions present themselves.

In some ways yes, at least anything young and reasonably good looking. In the right environment they would. The fantasy of being ship-wrecked on an island of a hundred young women with no other men. Women really would not even entertain the horror of the reverse for them. That environment would have very different consequences for both the men and the woman depending on the sex that was one and the sex that was the hundred.

You are saying that pretty much everything we do is from learning. If so then anything should be possible.
Though you talk about innate constraints you have not mentioned one.
All you have done is react to any suggestion of evolved behaviours as probably being a case of not seeing how these behaviours are in fact learned.
This very strongly suggests that you think learning is the main factor in our behaviour so in theory humans are so empty of innate constraints that they can be taught to accept any social system. Or mating system.

Do we educate them both to enjoy the porn or both not to enjoy the porn?
If the pleasure or pain each feels about this is just because they have learned to view porn differently what should we start teaching our sons and daughters? That they both should enjoy it or neither should.
Women taught to enjoy DP and 'facials' etc etc
There was some psychology I seem to remember (Freud?) that concluded that women are naturally masochists.
I can't wait for the new world where women ask each other 'does he swallow menstrual blood?'

No problem? You think?
I don't get what any of this has to do with the topic.
Really?
Aren't we talking about how we learn to behave the way we do and how the sexes are or are not the same?
Perhaps that there is no innate conflict of interests between the sexes, only learned ones?
That the constraints removed from women lead to greater 'male-like' behaviour ie more promiscuity, so should we also not expect that when the constraints are lifted from males we'd expect a movement away from porn and towards romantic fiction?
Or does removing those constraints only lead to increased promiscuity, not less? Why would that be if there is no 'natural' place for our behaviour to go to when constraints are removed. Does the removal of constraints lead to more 'natural' behaviour or to just a different kind of learned/constrained behaviour?

Fortunately, nobody has suggested that. With regards to sex specifically though, I'm yet to see any evidence that men are biologically more promiscuous than women.
Because they are sexually rejected more often than women are. And women are not doing this for any other reason than they don't want sex.

sprite wrote:Mr.Samsa wrote:That's a problem with the legal system and irrelevant to our discussion.
But part of the problem within the legal system is that the people within it think men and women are the same and so women are lying about not wanting sex when some degree of sex play has occurred on a date. Or some degree of flirtation at work. When a man does that he's not doing it to then say no to sex so the woman is lying.
sprite wrote:Mr.Samsa wrote:Regardless, the point is that there are differences in how men and women view sex as a result of learning. Surely this isn't a controversial position? The fact that for centuries (or longer), society has dictated that women should be "proper ladies" and induced guilt-trips on any woman that dared have sex, accusing them of being "whores", "sluts" and "slappers", and you're thinking that this wouldn't affect how they view sex?
Of course it does.
But that does not make a male-like female promiscuity any more real. All it means is that women are not naturally monogamous. I've said that. It is obvious. It's the same in most other species yet it is still that males are rejected more, seek sex more persistenty, females resist far more than males. When females are promiscuous it is under different conditions from male promscuity. Promiscuous species have things like large testicles, copulatory plugs, chemicals in sperm connected to sperm competition and female reproductive tracts that sort the sperm. Physical traits and behaviours are connected.
sprite wrote:Mr.Samsa wrote:So it is "arguably true" in that as long as you're talking about sex with the intention of reproduction, then yes it's about the transference of sex cells.
From the male to the female - never the transfer of eggs into the males body. Males have never had to deal with that at any time in our evolution.

I agree. In New Zealand this is what is happening since it has been legalised. They advertise it like any other job and they carry on with normal lives. Whether people want to date someone in that line of work is up to their own individual preferences - personally I wouldn't care, but I know some people would.

One in three women (32%) reported never or infrequently achieving orgasm during intercourse, with a corresponding figure of 21% during masturbation. A significant genetic influence was seen with an estimated heritability for difficulty reaching orgasm during intercourse of 34% (95% confidence interval 27–40%) and 45% (95% confidence interval 38–52%) for orgasm during masturbation. These results show that the wide variation in orgasmic dysfunction in females has a genetic basis and cannot be attributed solely to cultural influences. These results should stimulate further research into the biological and perhaps evolutionary processes governing female sexual function.

One male prostitute I heard said he loved his clients, mostly having a small number of regular ones. He came across as something like a silverback gorilla with a harem.

So to go back to the antler analogy, while the differences in the existence/physical structure of the antlers will affect the behaviour of the sexes, these behavioural differences would then be a product of learning? The females don't compete for males because they don't have antlers and learn that they don't so don't try to fight. The males learn they have antlers and that they can use them in competition with other males. Ummm....
Or we could say that the ancestor had males that competed by knocking heads. Some genetic variation occurred where some individuals developed hard growths on the head. This would initially have occurred in both sexes. Sexual selection and the action of establshed mechanisms to sexually limit the expression of genes that are adaptive in one sex but not the other leads to gradual increase over time of the evolution of the male antlers and the absence in the female.
I.e the behaviour of male-male competition shaped the selection of the genes for antlers in males while females did not have the same behaviour so the antler development was selected against.

Well incest avoidance is the basic one. In all social species one or both sexes disperses. Females especially resist incestuous matings.
Usually it is males who disperse as mother and offspring formed the first social unit, then daughters staying around while sons seek novel females.
Some change in apes led to sons staying with fathers and daughters then leaving to seek novel males and avoid incest.
We have it to some degree in gorillas which have one male or a male and son with unrelated females who move between silverbacks.
When the female bonobo reaches puberty she stops her sexual interactions and moves to the periphery of the group and then disperses. Maybe moving between groups before settling in one. This is where these otherwise promiscuous females exercise 'female choice' - they choose which community of related males they will mate with.
Incest avoidance with the attraction to some degree of novelty goes right back to the first sex cells.

Because they all boil down to the same species-wide principles of sexual selection, control over reproduction, and sexual conflict.

Insects have the most diverse and rapidly evolving genitalia of all species. They are the main subjects and evidence for Eberhard's work on female cryptic choice. Many species can ony be distnguished by the male genitalia. Females have their preferences for particular genitalia with particular stimulation. Sexual selection. Post-copulatory male-male competition plus post-copulatory female choice.

So what do we actually have going on here with this 'learning'? We have a damselfly female with a mating preference for darker wings. If she is just with her own males, no problem. But when in an area with another species that is externally much the same as her own she mates with them too. Then his genitals do not match her evolved preference in her species. She can now distinguish between her own and the other species.

You might think that because 'learning' is involved that mate choice is not an evolved, adaptive behaviour in this species. But of course it is. It's just that the evolved adaptation concerns the genitals with copulation needing to be in progress for female choice to act.
Here we have something which on the surface looks like 'learning' but these species have always and still are making mate choices through evolved preferences for particular male genitalia.

Yes it does because it is the production of eggs and sperm that in most instances determines how selection will act differently on individuals of the same species. If we were hermaphrodites then sex differences would not exist.
With two sexes comes two (often very) different environments for male and female, ie one has the environment where they must reproduce only with males, the other only with females. Bodies and behaviours diverge. That's just a fact of life. Males and females of the same species exist in different reproductive environments.

Or we could say that the ancestor had males that competed by knocking heads. Some genetic variation occurred where some individuals developed hard growths on the head. This would initially have occurred in both sexes. Sexual selection and the action of establshed mechanisms to sexually limit the expression of genes that are adaptive in one sex but not the other leads to gradual increase over time of the evolution of the male antlers and the absence in the female.
I.e the behaviour of male-male competition shaped the selection of the genes for antlers in males while females did not have the same behaviour so the antler development was selected against.
Indeed - so we would have two equally plausible hypotheses. We would need to test them to figure out which is which.

There was no overall preference for darker wings - the preference changed depending on their learning histories.
This suggests that the allopatric C. splendens females perceived these conspecific males with enlarged wing patches as extra attractive mates............
The strong positive female responses in allopatry suggest that female preferences are open-ended in favor of an exaggerated version of the basic male signaling trait in C. splendens, that is, the dark wing patch. Sexual selection will not conflict with
species recognition in these allopatric populations, because of the absence of heterospecific C. virgo males. Allopatric C. splendens females can and do thus show an increased preference for large dark wing patches, because they do not run any risk of mating with a heterospecific males. Although one might expect a conflict between species recognition and sexual selection in sympatry (Fig. 2B), such a conflict would not exist in allopatry at all, because there are no C. virgo males. This is the most likely explanation for the open-ended preferences in allopatry in which females clearly preferred males with entirely melanized wings.

Insane reinterpretation of the data... You're completely misunderstanding what learning and behavioral adaptations are.
The mechanisms for such aversive learning are still unknown, but they might have their origin in the physical interactions the males during the cage exposure experiments. For instance, heterospecific males might clasp females differently than conspecific males, or there might be a poor mechanical fit between the genitalia of males and females in the heterospecific couples (McPeek et al. 2008). Slight interspecific differences in fine-scale genital morphology (McPeek et al. 2008), might be perceived as tactical cues by females. There might also be behavioral differences between the species in how the different male types interacted with the females. These factors could provide the negative feedbacks that shape the final mate preferences in females, and the result might be an increased aversion against heterospecific males in sympatry.

You really think we need to test whether male deer evolved antlers and then started using them in competition with males? Why did they not continue to develop in females if they had no costs? And this would, of course, be going back to the first ancestor where the antlers evolved, not the current species where the sex-limited mecahnisms are already in force.
You think only male deer ancestor evolved the antlers first from the start and then it was case of 'uh, what shall I do with these?'![]()

The antlers are regrown for each mating/rutting season - again, clearly connected to male-male competition.
In caribou both sexes have antlers though the males have theirs for the rutting season and the females have theirs for the winter.
They were selected for in males due to their advantage in male-male competition, something which existed before the antlers evolved.
They were not selected against in females - or they may have been in the ancestor but again appeared in the caribou female and were then selected for in the females but with a quite different ontology than in the male, again no doubt connected to sex-limitation mechanisms - the female advantage was experienced in the winter months in competition with males over food.

Whether people want to date someone in that line of work is up to their own individual preferences - personally I wouldn't care, but I know some people would. But we have to keep in mind that this doesn't just apply to prostitution - there are people who refuse to date people in the army, tax collectors, etc., so there's nothing significant about choosing not to date someone who has a job that disagrees with your own principles.
So these jobs and advertisements etc are in similar numbers for both sexes?
Or is it still a service almost always provided by women to men?
Should we not work to open it up to men, like is done with traditional 'men's' jobs?
It is open to men too, and it is fairly equal - probably about 60:40 women to men. And if we were to include similar professions, like strippers and escorts, then I imagine it would be practically 50:50.
Mr.Samsa wrote:sprite wrote:There have been studies too that show women more consistently have orgasms in long-term, secure relationships.
Connected to this there is this study Genetic influences on variation in female orgasmic function: a twin study:One in three women (32%) reported never or infrequently achieving orgasm during intercourse, with a corresponding figure of 21% during masturbation. A significant genetic influence was seen with an estimated heritability for difficulty reaching orgasm during intercourse of 34% (95% confidence interval 27–40%) and 45% (95% confidence interval 38–52%) for orgasm during masturbation. These results show that the wide variation in orgasmic dysfunction in females has a genetic basis and cannot be attributed solely to cultural influences. These results should stimulate further research into the biological and perhaps evolutionary processes governing female sexual function.
Sure - and now demonstrate that this is an evolved trait. Remember our discussion about how biological functions can be appropriated by learning mechanisms?
Mr.Samsa wrote:All anecdotal though. I've heard the opposite - that most female prostitutes think that their clients are generally sweet and they do what they can to make them happy and comfortable because they care about them, to some degree. Whereas the male prostitutes tend to dislike their work more because they are usually lumped with uglier, older women. Unless we have any evidence to suggest which is right (if either), then the position is moot.

Perhaps, but you have to remember that it's incredibly difficult for men to do so given the current cultural demands. If a man notes that he doesn't watch porn or masturbate, what happens? He gets laughed at and called a liar. A man says that he doesn't approve of sleeping around? He's suddenly a "faggot" (and, depending on the idiocy of the company he keeps, he gets his ass kicked for his troubles).

Just in case you don't understand the distinction here, look at it this way: pain is a biological response, and arguably we could say that the retraction from pain is an "instinct". Now suppose I taught my dog to run around a ridiculous obstacle course including see saws, slalom poles, and a part where it has to roll over, shake paw, and yodel to the latest country singing sensation, and I did all this using the pain "instinct". Undeniably, these behaviors are learnt and no one would argue that the yodelling to Garth Brooks is an instinct in the dog.

The only statistic I can find is that 4% of rapes are done by women - however this obviously doesn't tell us whether there is any difference in the number of rapists (i.e. it could be that there are equal numbers but men are simply more prolific).
So obviously your statement above is flat-out, completely and dangerously wrong. Even if we accept that it happens "relatively rarely" (a claim that is disputed in the literature on the subject), this doesn't change the fact that your ridiculous belief that men aren't raped by women to be absolutely bogus.
Mr.Samsa wrote:Except this isn't the only factor for marriage, and what people report is usually very different from their actual behaviors (hence why self-reported data is generally pretty useless).

LONDON: If you think your macho look can make you a hit among girls, think again - women find men with feminine faces more attractive, claims a new study.
Psychologists at New York and Princeton universities found that most women prefer men with more feminine shaped faces and darker skin.
But the study found that men typically like women's faces to be feminine with plump lips and wide eyes. For the study, the researchers recruited two groups of men and women and showed them a selection of thousands of computer-generated faces of the opposite sex to rate, which had been manipulated to look either more masculine or feminine.
The computer model tested 50 dimensions of facial features, including nose size, plumpness of lips and complexion. The scientists found that more men want women's faces to have a feminine shape, while women want men's faces to have a feminine shape, but darker skin.
The findings showed that male and female attractiveness are not equal and opposite. They also found that the appeal of average faces is less straightforward than previously thought.
The study, to be published in the Psychological Science journal, showed that attractiveness is more complex than had been found by previous studies, the researchers said.
While both men and women find average faces attractive, the most average faces are not considered the most attractive, they added.
