One of my first girlfriends told me about how just after a dance, her date had gotten drunk and felt her up. All night long he kept groping her, sometimes in front of her friends, and it really pissed her off. After the dance they went to a friend's house and he passed out on their couch. She was really mad at him for constantly groping her, so when everyone else had left the room, she got up, punched him full force in the balls, and walked away. A few seconds later, he woke up, doubled over, and threw up.

He didn't know she did it, and she felt bad about it, and wanted to know if she had possibly permanently damaged him. I told her that I seriously doubted he was "damaged" and not to worry about it. I talked to him the next day and he said it was the alcohol that made him throw up, so I guess he never found out
