This is like the opposite to a traditonal slut who is a woman that will give away sex without any type of a relationship.
No. He just hangs off her and does whatever she wants. He is basically her manslut. I've seen him do the same thing with other women. He just doesn't realise that some women will be a bitch, and use him.
Poor guy, someone needs to help him out. He needs to be a bit more of a stud.
Susan: You're such a man slut. I hate you.
