"Ew, God no"? Seriously? Testicles are *interesting*. They change shape with arousal. They move around, they firm up. And the skin is all wrinkled, and it moves -- all those wrinkles sort of undulate. It's very cool. So it's kind of nice if your guy shaves 'em. Not so his dick looks bigger (only guys really believe bigger is better), but so you can see.
