I do like the idea of the novel of repressed college students being a contemporary novel of courtship! I guess what I would say to that is, we tend to think of historical periods and historical mores as ending a lot more concretely than they do. Like, in an Austen novel, there are lots of reasons - cultural, moral, religious - why the characters don't have sex during courtship. Maybe, even though those reasons have kind of expired, historically, they're still around in some sense.
