It probably depends on whether you're focusing on the pleasures or consequences. Which probably correlates with your social/political bent. Since it seems to be conservatives who complain most frequently about the environment of college campuses, the frame of the discussion might be directed to conservatives, who are more likely to focus on the consequences and find that a positive note.

And yes, we're better as a society at statistically mitigating the some of the consequences of intercourse, but that doesn't mean they don't exist, and that younger & unmarried folks are probably less prepared to deal with them, so there's a reasonable (although limited) general argument that less pre-marital sex among late adolescents is a turn towards more responsible or at least age-appropriate behavior.

There are other reasonable approaches to the topic as well.
