Casual sex is a poor long-term strategy for both men and women as it prevents the formation of necessary, stable, and iterated partnerships.

“if you develop a long-term partner in a woman and you're a man, you might want a woman who has enough sense to move from maiden to mother to matriarch and to do that in a manner that facilitates the uh you know, the development of the relationship across time.”

Casual sex is less empowering than traditional relationships, and the modern expectation that women should participate in it leads to unhappiness.

“many of the young women who um who've read my book have been raised with this expectation and have attempted to have sex like men and have invariably found that it actually makes them miserable”
