I did a few times when I was in college. It was always when I was alone with one guy and there was almost no risk of being caught. Today in middle age I am ashamed of myself for being so desperate and needy and careless. I don't like seeing sexual graffiti in men's rooms and I especially hate sexual activity in public bathrooms. We gay men should have more self-control, especially if we hope to squash the stereotype that we are all sex-obsessed. Looking back I am embarrassed at the few times I had sex in showers and wish I could undo those actions.
