To me it's hard to imagine a woman being physically abused by a submissive man who respects and appreciates woman though that's just an assumption which I could be wrong about. It also seems to me curious that woman anecdotally seem to be abused when they are in their 20's rather than their 30's and older. Although it would probably be easier to hide abuse with someone you're married with, in a casual relationship there's more room to feel contempt for your partner
