Here is Charles Busch:
Years ago, I played Orestes in a homoerotic production of Jean-Paul Sartre's The Flies. All the guys wore extremely short Greek tunics and primitive G-strings underneath. Whenever I'd raise my arms to the Heavens, the tunic would rise and my bare ass would show. The giddy gay audience would hoot and holler. I shouldn't complain—when the actor playing the king was slain, his G-string slid, and he had to lie dead for the rest of the scene with both testicles hanging out.
