Her idea of rough sex is beyond rough-it's sexual abuse. Good for you for NOT wanting to participate. The physical differences of male to female while it may excite her-could end up resulting in her death. I'm sorry, but I would not be surprised if she ends up in the newspaper under "Death by misadventure". That would be why she is your ex.

You don't need her and you arnt a wimp.you seem quite capable of giving her a sound beating.
She wanted to make love to you or have a fist fight. The girl was twisted its good you got rid of her
