Good night, kids

Same-sex bathrooms and liberal "visitation" policies are no longer uncommon at major universities. The University of Massachusetts, for example, has only three same-sex dorms. The bathrooms in the co-ed dorms are not shared between men and women, but residents in any dorm may have guests of either sex stay overnight. There are some limits to that; after three nights of hosting a guest, a resident is supposed to wait a couple of weeks before having a guest again. These policies are not heavily enforced,

however.

At the University of Michigan, overnight visitors are allowed, as long as a resident's roommate consents, and only for a total of six nights per month.

Co-ed bathrooms are common at the University of California at Berkley, but there are single-sex dorms and freshmen are allowed to live off campus.
