Again, I gotta ask: if female organism is a straightforward adaptation, shouldn't we see a higher prevalence of "orgasm during intercourse" women? According to CB's adaptionist story about female orgasm is a means of encouraging sexual activity and thus procreation, shouldn't all the women who were genetically predisposed not to have orgasm during sex have been culled out of the human species long ago?
This looks more and more like an excellent example of G's spandrels to me.
