Some girls tell me maybe the reason why it hasn't quite hurt other girls as much as men getting nut shots because people tend their strikes inaccurately and end up missing the critical spot, the clit. For striking men down their on the other hand, it's too damn easy to land the strikes on men's balls because they're much bigger and more exposed.
Sorry, but even missing the clit and getting kicked in the general vaginal area would still hurt. Anybody that doesn't think that it wouldn't hurt and shouldn't be sold is a bit of an idiot.
