But fear is probably not the only reason for the gender convergence. While American locker-room and popular culture portray boys as mere vessels of raging hormones, research into their private experiences paints a different picture. In a large-scale survey and interviews, reported in the American Sociological Review in 2006, the sociologist Peggy Giordano and her colleagues found teenage boys to be just as emotionally invested in their romantic relationships as girls.

The Dutch boys I interviewed grew up in a culture that gives them permission to love; a national survey found that 90 percent of Dutch boys between 12 and 14 report having been in love. But the American boys I interviewed, having grown up in a culture that often assumes males are only out to get sex, were no less likely than Dutch boys to value relationships and love. In fact, they often used strong, almost hyper-romantic language to talk about love. The boy whose condom broke told me the most important thing to him was being in love with his girlfriend and “giving her everything I can.”

Such romanticism has largely flown under the radar of American popular culture. Yet, the most recent research by the family growth survey, conducted between 2006 and 2010, indicates that relationships matter to boys more often than we think. Four of 10 males between 15 and 19 who had not had sex said the main reason was that they hadn’t met the right person or that they were in a relationship but waiting for the right time; an additional 3 of 10 cited religion and morality.
