Are you seriously suggesting that a grown adult without any mental handicaps, could be unaware as to whether or not they have been assaulted?
Here is a small exercise, apply that to any other crime that by nature involves physical contact.
Would you be "unaware" that you had been sprayed with paint by some PETA clown upset that you keep snakes?
Or after being beaten and robbed be "unsure" of what happened.
Don't be all butt-hurt about being identified as sexist for your view that men should be assumed to be criminals.
