About 75% of the cultures in the Human Relations Area Files practice non-monogamy, so that doesn't support any idea that monogamy is particularly natural.
I don't think monogamy is a sexual neurosis. It works for many people, but not all, and probably only a minority. There are two things about monogamy that are, if not neuroses (which is an outdated term anyway), at least a bit nuts.
One is an expectation that everybody be monogamous, to be enforced by laws and shaming. This is like expecting everybody to be heterosexual or Christian.
Another is what is called "serial monogamy," which would more accurately be called "serial non-monogamy." Very few people only have sex with one person for more than a few years. Some people's "monogamous" relationships only last a few weeks. Monogamy works when two people are happy being monogamous until one of them dies. People who practice "serial monogamy" want to think of themselves as monogamous when they really aren't.
As for paedophilia and and incest, I think that if informed consent isn't given, then it's wrong. I don't think children can give consent for sex until they are old enough to make decisions about other aspects of their lives, or until they actually understand the consequences and side-effects of early reproduction, or are mature physically to reproduce without potentially dangerous side-effects. But that's my personal opinion, not science.
Almost all people seem happy with the decision that sex is only appropriate for consenting adults.
As for incest, I once read a story of a female gorilla raised by humans who, whenever she went into oestrus, avoided the male members of the family like the plague. This suggests the possibility that there is an innate tendency to avoid it, which is only broken in cases of particularly odd individuals or royal marriages. It may also be related to what some people have called "familiarity incest," which may be a force working against monogamy.
