Netphoria Message Board - A question for those of you with relationship experience

First of all, as is widely known here, I am only sixteen, so don't take anything I say too seriously. This is just a sixteen year old's perspective on things.

Ok, so I've been in a relationship for over four months now. I know, not very long, but for high school standards I think it is. I love this girl very much. We are pretty good for each other, I think. We spend lots of time with each other, we're always all over each other. It's my first real relationship. Recently I have been thinking a lot about how different we are though, and how I could find someone better for me. Don't get me wrong, I am still infatuated with this girl. I really really love her. But at the same time I feel that maybe I need someone more...punk rock? I keep envisioning this rock and roll chick who would be into my music and view on the world and stuff, and we would be perfect together. My girlfriend and I are very happy together but there are a few things that she lacks that I always thought I would look for in a girl. First of all, she's too into pop culture for me. She likes stupid pop culture movies (like American Pie and Titanic) and listens to too much pop music (Ashlee Simpson, although she likes rock too). I'm thinking, maybe I need a girl who won't get pissed when I make a big deal about going into Hollister? Secondly, she's not very adventurous. She always wants to plan things out neatly and do everything the safe way. She's not very spur of the moment. I wanted to stand in line for the Billy Corgan show nine hours in advance to assure that we had a stage front spot. She made a huge fuss over it and we didn't get there until 2 hours before. I want someone who will stand in line with me for hours and hours at concerts. I mean, we're fucking sixteen, this is what you do when you're young. She tells me sometimes that I need a haircut, or that I need to stop wearing so many band t-shirts.

Anyway, none of these things bother me that much though. I am totally in love with this girl and I don't care most of the time. I think she's wonderful and I am always counting the hours until I get to see her again. But then, in the back of my mind, I start thinking of some punk rock chick who loves my music and shares my crazy anti-establishment beliefs...someone just like me, who could come into my life and we would be even MORE perfect together.

Is this normal? Should I just quit bitching because I'm only sixteen? I dunno. It's not like, a huge conflict in my mind either, it's just something I've been thinking more and more about.
