It can happen, but statistically adult man vs adult woman is not a fair fight.

I knew a guy at university; started going out with this smoking hot girl. She was a regional champ in jujitsu; it didn’t last long, turns out she was a violent piece of shit. Beat him up twice, he left after the second one. She had major anger management issues.

But you turn that story around a little, similar situation, girl has same anger management issues, but without the training etc, she is unlikely to be a threat to any adult guy.
