I"m sure they exist but I've never met a man afraid of his wife beating him.    I do however have a woman friend who did the classic frying pan into her hubands face.

But what's your point?  Are you saying bad behavior by one sex justifies bad behavior by the other.?   
                                              Are you saying sexual assault or abuse is equal on both sides?
 
I really not sure what we're talking about at this point?
