The National Longitudinal Study of Adolescent Health data offer other glimpses into just how low the cost of sex is for young men ages 18 through 23. Take the speed with which these men say their romantic relationships become sexual: 36 percent of young men's relationships add sex by the end of the second week of exclusivity; an additional 13 percent do so by the end of the first month. A second indicator of cheap sex is the share of young men's sexual relationships—30 percent—that don't involve romance at all: no wooing, no dates, no nothing. Finally, as my colleagues and I discovered in our interviews, striking numbers of young women are participating in unwanted sex—either particular acts they dislike or more frequent intercourse than they'd prefer or mimicking porn (being in a dating relationship is correlated to greater acceptance of and use of porn among women).
Yes, sex is clearly cheap for men. Women's "erotic capital," as Catherine Hakim of the London School of Economics has dubbed it, can still be traded for attention, a job, perhaps a boyfriend, and certainly all the sex she wants, but it can't assure her love and lifelong commitment. Not in this market. It's no surprise that the percentage of 25- to 34-year-olds who are married has shrunk by an average of 1 percent each year this past decade.
Jill, a 20-year-old college student from Texas, is one of the many young women my colleagues and I interviewed who finds herself confronting the sexual market's realities. Startlingly attractive and an all-star in all ways, she patiently endures her boyfriend's hemming and hawing about their future. If she were operating within a collegiate sexual economy that wasn't oversupplied with women, men would compete for her and she would easily secure the long-term commitment she says she wants. Meanwhile, Julia, a 21-year-old from Arizona who's been in a sexual relationship for two years, is frustrated by her boyfriend's wish to "enjoy the moment and not worry about the future." Michelle, a 20-year-old from Colorado, said she is in the same boat: "I had an ex-boyfriend of mine who said that, um, he didn't know if he was ever going to get married because, he said, there's always going to be someone better." If this is "the end of men," someone really ought to let them know.
And yet while young men's failures in life are not penalizing them in the bedroom, their sexual success may, ironically, be hindering their drive to achieve in life. Don't forget your Freud: Civilization is built on blocked, redirected, and channeled sexual impulse, because men will work for sex. Today's young men, however, seldom have to. As the authors of last year's book Sex at Dawn: The Prehistoric Origins of Modern Sexuality put it, "Societies in which women have lots of autonomy and authority tend to be decidedly male-friendly, relaxed, tolerant, and plenty sexy." They're right. But then try getting men to do anything.
