This is definitely rape in my book. I don't care if they're asleep or not! I highly doubt he was sleeping anyways! I like the knife idea! You need to let this man know you mean business and that what he is doing is a serious crime! You don't have to take this EVER!

I'd threaten him with going to the police if it happens again. Then you can tell him the consequences of doing it again.

I believe people can do many things in their sleep, but sex is not one of them!
