But chastity groups seem to be on to something — a growing unease that although hooking up can be liberating, it can also be annoying and sometimes destructive.

“It’s a huge part of life here,” said Maariya Bajwa, a senior at the University of Florida. “When I used to take the bus I’d hear random people having conversations about random hook ups they had. I was like, ‘Uh guys, we’re on a bus. I don’t need to hear about your one-night stands.'”

By the end of senior year, the average college student has had 6.9 hookups, mostly after a “good bit of drinking,” according to a survey of 4,000 students at five universities by Stanford University sociology professor Paula England.
