Yeah, I know this gets posted a lot, and I was even able to find some advice on other forums through a Google search, but I wanted some fresh input, and I wanted to state my situation a little bit more specifically.
I met a new girl about 3 and a half weeks ago. I'm 23, she's 21, going on 22. We met at a punk rock bar, which is something we are both very much into. I got her number and then asked her out for the following weekend. When we went out, we found out that we have a crazy amount of things in common. Into all the same rare music, movies, books, etc, which is hard finding someone with such subcultural interests. We went out a few other times and had a lot of fun each time. Our first kiss was on our second date, and our third was just the other night. (Not including the night we met.) On our third date, we were able to snuggle and cuddle, and kiss at will without any awkwardness or hesistation. We're going out tomorrow night again for our 4th official date, 5th night out total including the night we met. Tomorrow we will be going to a restaurant, which will be a great opportunity to sit down and get to know her even more, similar to our first date. I've already met her family as well.
So the question is, if you were in my situaton, when (how many more dates) would you ask the question to make things official? I'm not asking to marry her or anything, but I'd like to be able to call her my girlfriend, because I really do like her a lot, and don't exactly get interested very easily, so she is someone special.
