I was actually just reading about this stuff in 'The Moral Animal' by Robert Wright. Natural selection clearly explains why males (in nearly all species) are so much more eager to have sex than females. When it comes to sexual intercourse, males have close to zero investment compared to females. Males can leave immediately afterwards, whereas females might have to raise a baby, which is a huge burden. This explains why females are more choosy than males, in over 95% of species. "Lust is natural selection's way of getting us to act as if we wanted lots of offspring and knew how to get them, whether or not we actually do."
In addition there does not seem to be "a single culture in which women with unrestrained sexual appetites aren't viewed as more aberrant [atypical] than comparably libidinous men." This suggests that this might have been a universal cultural element that was present 500K+ years ago, when our species began spreading about the land.
It's very interesting stuff.
Been away for a bit, but sneaking back in.
