Hmmm, Personally (male), don't see why not. Infact have more femals friends I'd say that male. And by far my closest friends are girls. Doesn't mean I fancy all of um, just that we are very good friends!
You could, depending how your bf is, get him to say meet you after class, then when you and this other fella are talking you can introduce them? Who knows, your bf might get on with him?
(having said that, have been single all my life, but thats a different issue!)
