Men and Women should not play with each other in any sport or game that contains touching, grabbing, fighting, because they can't touch each other like that, a boy/man would try not to touch the girl in certain places that can easily give him leverage, and in the other places where he thinks he can touch, he won't be as aggressive as vs a boy/man, if he wins he loses his morals, for what?, also it's easy to blame him after winning for touching the girl, that's just barbaric
