II'm with Kinky Laughter here. Getting kicked in the lower extremity hurts even if yoru female!!! More then one person did it to me in a soccer game once because I think their coach told them too. I swear to you I wanted to hit that shim(she/him) in the crouch, just to see how she/he responded. Anyway thats beside the point.
I would never kick a guy in the nuts unless he was trying to rape me in which case he would fully deserved to be disarmed

. Its not even fair in a casual fight and its not even fair with casual flirting/hitting/messing around. From what I've heard it hurts so bad that you would rather have your arm ripped off. Unless you have those mighty balls of steel I heard some of my guy friends talk about. This senior (in my freshman year) got hit square in the gonads by a guy trying to start a fight. The senior looks down and didn't even make a sound when he started thrashing the guy. It was pretty funny, but a very unmanly way to start a fight if do say so myself. *nods*
