OK I used to go to school with this girl, we werent friends or really knew each other, but fast foward a few years and we ended up working together. We have very quickly become friends, we call each other and hang out alot. So last night she brings me with her as she runs some errands and we go back to her place and watch movies, her roomates are there for a few but all end up leaving. So were just hanging in her room watching movies, I'm sitting on the floor, shes on her bed, and she kepts saying stuff like "i don't have cooties, you can come up on the bed, etc" I didnt really want to because we had been outside in the heat and I knew I probably didnt smell the greatest, but after I cooled off I did get up on the bed, after a little while she starts texting someone and starts looking like she's waiting for me to do something.
I have been noticing a little sexual tension between us, like I have this hilarious sense of humor that girls seem to love, so shes always playfully hitting me, and a few days ago she was a little drunk and kept making little comments about me and her having sex, and yesturday I made this crack about her checking out my ass and she said something like "you want me to check out your ass"? I hadn't really found myself attracted to her before but now I am, but I have this nasty habit of misinterpreting things and ruining my friendships with girls, so I want to avoid that at all cost. Any comments/advice
