This quote from a book I’m reading for my dissertation, is particularly relevant to the debate on gay marriage:
A serious sex education begins by emphasizing the reasons why female sexuality is dramatically unlike male sexuality; it explains the natural reasons for female vulnerability. It explains to women why they like to be courted and how their sexual restraint can encourage a courting culture. It makes possible an education that does much more to rein in male sexuality.
The more serious studies of sex differences I read, the more ambivalent I become about gay marriage.
