I agree that more SD classes should be taught by women (that is why I do). Our self defenses classes were run by our school owner and master instructor who is male and his wife and myself. Plus we encouraged all of the black belt women at the school to attend to help out each of the women or to be their partner. What the male instructor was actually good for was being our punching bag and our "agressor"! He would instigate the women trying to evoke anger while holding target shield. When they would hear..."Aw c'mon is that the best you got??? (among other choice remarks!) You need to be able to have a male in the class in order to work your body mechanics against the opposite sex... to throw him off of you. By end of class when he was in full targeted armor the women went wild!! What a sight to behold!
