I have often felt that I just manage to tiptoe the line between addict and oversexed. Sessions between 4-8 hours are not uncommon for me over a number of days. My current girlfriend loves it but I have had complaints from others.
It sounds good but I have periods where it affects my concentration and in previous years under differeny employers I have been known to pull sickies and fake dental/doctor appointments to meet people for sex. There are times that it really isn't fun.
