I’m a sophomore at a Catholic college, and while I might be naive or in my own sort of bubble, I don’t think it’s as widespread as that article makes it out to be. We have a pretty (relatively) strict code of conduct…premarital sex can result in expulsion, and we have single-sex dorms and enforced visiting hours.
At least for students here, there is no precise definition of ‘hooking up.’ While it definitely is some sort of random sexual activity/physical intimacy, my own perception is that most students here who talk about ‘hooking up’ don’t mean actual intercourse. (‘Making out’ and perhaps a little more…)
Not that this is that much better, really, but I do think that overall there is at least some understanding that sex is more special than something to be shared in random encounters with an anonymous partner.
I’m positive that the same can’t be said of the vast majority of other universites in the US. Except for a few Catholic/Christian colleges who adhere to a moral code (I’m not talking about Georgetown here…), universities do little to stop anonymous sex or even make students aware of the emotional/physical consequences. Many even seem to encourage it by handing out condoms, sponsoring a ‘sex week’ (pioneered by that wonderful Ivy League institution, Yale University!), etc. It’s a scary world out there!
