How do you know that?
I would think that the experiences of the people on this thread (read the whole thing) would indicate that it DOES happen, and not infrequently.
I know that because of the work I do
You can add me to that list.
I was raised never to hit a woman, and I never have. I have dodged plates and pans, and when I grabbed her wrists one time to keep her from hitting me, she leaned in and gnawed a chunk of flesh out of my wrist (I still have the scar).
No, I never reported it because I didn’t consider myself seriously hurt and I still loved her up to the point where she threw me out because she “wasn’t feeling fulfilled”.
Most guys won’t report it, but it happens a lot.
