For example, grabbing a cock and squeezing or twisting doesn't cause much pain unless it is hard but anything with the balls (hitting, squeezing, etc.) is incredibly painful. Will any of the women here please discuss which crotch attacks are easiest to execute and which are most painful? They may not be the same things since women don't have anything as easy to grab as a ball sac.
Kicking or punching at the pubic bone would seem the best striking target but maybe I'm wrong? Grabbing the area around the clitoris and pinching, twisting seem the most common non-striking attack so I'm guessing that is more painful than clawing at the vulva. How about pulling or twisting the lips? Scratching inside the vagina? These are a few examples of what I think would be the answers but as a guy I can only guess. Love to hear the "real truth" from the women!
