I was in this very position not too long ago. According to my notes, you should not treat her like a queen all weekend like previously advised. She'll know you were putting on an act if you do. What you should do is maintain a slight indifferent and noncommittal attitude. When you go out this weekend, don't get all dressed up and stuff, at least not all weekend. You should show up in a t-shirt and jeans for at least one of the dates (a Halo 2 T-shirt is preferable...it's all about attitude). Also, if you're lucky enough to score, don't get all excited and sh!t. Tell her "Meh, it was alright." This will make her bang your brains out the next go round to prove to you that she is all woman. If you were stupid enough to tell her that you were a virgin and she brings that up after you give her the line above, tell her you were lying so that she wouldn't think you were only after her for the coochie. Stop with the long and drawn out kisses. That's so virginy.
This advice will work, at least for the weekend. That may be all you want by the time it's over anyway.
