That is true, it's pretty much the first defense any woman will go to. It will certainly send a man to his knees. BUT we can't assume that they aren't prepared for a swift kick in the nuts.
Most predators assume that they will be able to overpower women - they assume that we will be subdued before having the chance to kick them there. That's why it's a good idea to learn ways to get out of a hold (twist the arm, throw yourself over, use your body weight, etc) and THEN kick them. You can't count on just the kick to get you out - they need to be off balance, confused, and not ready for it.
My boyfriend has taught me the best way to get out of every single hold a guy could get me in, and then what the most efficient way to knock them out is, whether is a knee to the face or to the balls.
I completely recommend either a guy friend with a martial arts history, or a self defense class. I feel so much more prepared just knowing that I could get away if I had to.
A few tips I learned -
- use your body weight against the attacker. If he's pulling you, and your resist, he will over power you. But think about when you're trying to open a door and it's stuck.... you pull and pull and when it finally comes your way, you fall down from the momentum - same deal. Resist them then let your body weight knock them down by changing directions. They'll fall and you can do what you have to get away.
- use all your resources. Make NOISE. Scream, kick, scratch, go for eyes, mouth, bite, hit, whatever. Become as much a hassle as you possibly can. Flail, fight, twist, flip, whatever you have to do. They are looking for easy prey. When you become trouble, it's much easier to find someone else. Think about it - most kidnappings are sex related.... what good are you if he can't subdue you? Obviously it's not ALWAYS the case, but usually, when you become a hassle, they'll leave.
