It's just a sad fact of life unfortunately. Some guys think any girl who talks to them wants to date them and then says girls are bitches when they reject them. On the other hand there are some girls who thinks every guy who just looks at them wants to date them and nothing you say can change their mind. I haven't had a friend like this fortunately, the worst I've had is a guy not understanding that not only did I not want to date him I didn't even want to be his friend. Even after 2 years of not talking to him at all he still doesn't get it and called me up asking if I wanted to hang out the other week.
It sounds like your friend just needs a really good confidence boost though to help him out. Hopefully he finds a way to control himself so he doesn't scare away any potiential girlfriends. Most you can do is what you're already doing and just let him know when he's gone too far and give him advice.
