a couple of weeks ago the head of my, um, "unit" was squashed flatter than I would have ever imagined possible. It was bad enough I had to run to the bathroom and make sure it didn't split down the sides. I still got the armbar, and I still had sex that night. I haven't told my wife that story, she would make me start wearing the cup. It's just like in chess, though, sometimes you have to sacrafice a major playing piece to maneuver into checkmate.
