HOW LONG DO GUYS WAIT BEFORE ASKING GIRL TO BE GIRLFRIEND?

Almost 2 months ago I was introduced to a guy through mutual friend, and we hit it off right away. He's 27, I'm 25. We see each other at least 3x a week including sleepovers. Neither of us is talking to or seeing anyone else -- I'm sure about this. Its been a while since I was in a relationship so I'm not sure how long it usually takes for a guy in this kind of situation to ask a girl to be his girlfriend?
