David Puts is a Professor of Anthropology at Penn State whose research focuses on the evolution and development of human sexuality and sex differences. Apparently women orgasm. Why they do it however, has been a mystery for a long time. They don't need to in order to get pregnant. And sometimes they don't do it at all, for ages. So what use is the female orgasm, and what predicts the sort of partner who'll make it happen? Expect to learn if the female orgasm is just a gatekeeper for oxytocin, whether more dominant male faces predicted earlier orgasm, why men competed for women through contests rather than sexual selection, how male-male aggression, not female selection drove the evolved differences between men and women, whether you can tell a person's personality from their voice pitch and much more...
