I really like this girl and she likes me but im not sure what to do with her.
I really want to have sex with her but I don't think she wants to have sex. She is really laid back and shy and nervous and just plainly isn't into romance that much. At first when I met her all I wanted to do was screw her but now I actually have feelings for her and I love her with all my heart.
She is downright beautiful and sometimes I just cant control myself. Maybe I should wait a bit longer because we are still pretty young but if we break up I will never forgive myself for not doing her because that's been my dream for a while.
Im so confused. 
Ill try and talk to her I guess.

You need to talk to her. How will you know what she feels and what she may or may not want unless you talk to her?
My guy was my first for...everything.
I was somewhat shy (not as bad as I used to be, but still, kinda shy) and he kind of new from the beginning that I dismissed a lot of things when it came to guys because of the weird people I had attracted in my past. I kinda kept things that bothered me to myself as a long time ago I just learned to shut up because people either implyed or told me I was stupid for saying things or told me I was wrong.
But we started talking and I let him know that I was a virgin and had never done it or kissed anyone or been felt up and etc etc. And that lead to conversations over the phone asking if he could do things like touch my breast the next time I saw him and etc etc. It eventually lead to me making up the decision (yes, I made it and he didn't pressure me at all) that I wanted him to be my first.
It's been a little over two years since those conversations started. We're not dating and we never have been. However, he's one of my best friends, (as only a best friend can somehow or another manage to drag things bottled up inside of you out and make you confront your fears of talking to people about things, even when you really don't want to) and we have a little bit of benefits on the side every now and then.
And after all it's over, if it's ever over, we've promised to keep in touch and stay friends.
So, anyways, enough about me. Talk to her. You never know where it can lead.
If you really have feelings for her, then it's worth taking your time and making sure that everything goes well. Try talking to her about your feelings and see how she feels. Communication is the best and easiest way to make sure that there aren't any misunderstandings.
Good luck.
