This essay, to be published in Boston University Law Review’s symposium on Hanna Rosin’s book, The End of Men, challenges Rosin’s suggestion that contemporary sexual norms on college campuses serve women’s interests well. Unpacking the same data that Rosin uses to defend hook-up culture on women’s behalf, the essay argues that hook-up norms facilitate rape and may help explain the high rate of sexual assault on college campuses. Hook-up norms also perpetuate the sexual double standard, disproportionately hurt lower income women who cannot compete in hook-up status games, and valorize boorish, selfish male sexual behavior. In doing so, hook-up norms likely hurt young women’s ability to secure what they say they eventually want, which is sexual relationships rooted in equality.
