Questions: Guy's Behavior

I know it's a bit of a silly question, but this is something I've wondered for awhile. We all know how a kick to the groin for men hurt, but it also does to women.

Men have their stuff hanging out, while we have our stuff in. Everyone thinks that makes them more sensitive... but we also have the clitoris (which is WAY more senstiive than whatever a man does), and the bone, which is weak to any pain.

This is probably a really dumb question, but I was talking about this in a self defense class, and I feel like people just pass it off on empirical evidence and stuff. Women would be harder to hit than men, but that doesn't mean it hurts less.
