Well. The ball part, that is something I never knew, EVER.

Can uh... Can some guy please confirm this? It's probably not as exaggerated as the image of disappearing balls I have in my head right now.

I guess I've never noticed that before?

Also, that's probably because only young (>35ish) and highly virile men can trigger that defense mechanism. The muscle isn't strong enough in other cases

Testicles can temporarily retract as far as the lower abdomen. So the skin and shit is still there but the ball part inside isn't.
