Some of the few exceptions occurred at the private Christian college I attended in the mid 1980's.

It just so happened that someone was "enjoying himself" in the shower at about 2 in the morning (we had a communal bathroom w/ showers), and was interrupted. Word got around. I never even heard the guy's name. But, I remember a guy that most of us liked commenting on it by saying, "I'm glad it didn't happen to me."

Another time, someone talked about how a group of guys saw something on the wall in the hallway, and the comment was made, "Looks like someone wiped out there." The guy telling the story wondered how the speaker knew what it looked like. Not unkindly. He just was making the point that everyone masturbates.
