I once allowed my ankles to show, sparking a scandal. Yeah, I attended college that long ago!
In the here-and-now, at The Kid's college nudity is allowed on campus, including the grassy parklike area facing the town's main shopping street. (It's allowed at the Other Kid's college, too, but it's fairly isolated.) Both kids report that full-out nudity is rare: the guy, and it's always a guy, usually wears shoes.
Fire safety laws have gotten draconian at both schools. Dorms removed curtains years ago, leaving the rods in place, but students are not allowed to provide their own curtains or to drape fabric or other materials. No candles can be lit, not even a birthday candle outside. At one school, there's a $500 fine for a black-wick candle (since that means it was lit).
Bisexuality, especially among women, is so common it's unremarkable at both their colleges. They both know transgendered people, too. Granted, these are liberal schools, but I was still surprised at how open and accepting the students are about everyone's choices. (Yes, there's a transgendered person, a biological male living as a woman, who considers herself a lesbian because she likes girls.)
