:no: Have you ever practiced or been trained in martial arts? I used to teach self defense classes in college (Jujitsu and Savate) and rule #1 is always to fight. Statics even prove in a male on female actual attack, survivors are the ones who fight.
In terms of a nut shot in the real world, it's a great move and delivered correctly is an excellent initial blow. I always teach the initial locations of vulnerability, groin, throat, ears, eyes, solar plexus, base of neck, etc....
Rule #1 on the street is to avoid showing off and kicking higher than the groin. Save the head shots for when they are on the ground. From an attack standpoint, a solid rear leg cross stomp to the side of the knee will take out most any size attacker. Quite possibly one of the best ways to immobilize them and easy as saying goodbye after a groin shot. Even an small framed soccer mom can execute both moves.
