Speaking for myself, it is a great turn on to break an unbreakable/unwilling woman so to speak. Forced, non-consensual domination of an once confident and strong woman is a favorite fantasy of mine. It's similar to male students raping a female gym (karate) teacher but it doesn't have to be physical. In fact, I prefer the woman to break down mentally or both. Forced to submit body and soul =P

Maybe this helps?
