I wouldn't worry. Based on what I"m hearing, I wish to god I was in your shoes. About 6 nights ago I slept with a girl who assured me that she was not slutty, and that what was happening that night was not something that she usually does. She also assured me she was on birth control, and neither of us had a condom, and considering I hadn't been laid in a year, I went for it. (I didn't finish, but it lasted for 45 minutes before I had to leave for class)

Now I find out that she DOES do this kind of thing all the time, that she slept w/ another person in teh same week, that she's PLANNING on sleeping with someone tomorrow, and that she's not on birth control. So, I'm pretty much ****ed on several fronts. Just thought I'd share in the hopes that my situation makes you feel better. Cheers!
