On an interesting note, I have found that when I role with Women and Adolescents I try and not go "easy" or be particularly genital with them.
They in turn tend to really enjoy rolling with me. As though they actually feel like they are being treated like just another person in the gym.
If I errantly place my hand on your boob if I am doing say something like a spinning armbar I will apologize for it in the same way if I nick my partners nuts. Truth is most sane women can tell the difference between someone doing something to sexual or not.
I think the fact I don't go to great pains to treat them different on the mat helps a lot.
**** whats the point of them even being there if they don't want to deal with a bigger stronger attacker?
