Apropos the Larry Craig public restroom suckoff event someone reminded me of a scene from Hunter Thompson's FEAR & LOATHING IN LAS VEGAS:

"He said nothing: Merely grabbed my arm and began sucking on it. A very gross tableau. I wondered what would happen if some Kingston Trio / young stockbroker type might wander in and catch us in the act. Fuck him, I thought. With a bit of luck, it'll ruin his life - forever thinking that just behind some narrow door in all his favorite bars, men in red Pendleton shirts are getting incredible kicks from things he'll never know.

Would he dare to suck a sleeve? Probably not. Play it safe. Pretend you never saw it..."
