What should I do the people I became friends with my first week at college I now realize their not good friend?

You're going to wind up in jail with a "friend" like that. Ok, jk... You're in college to study, so do just that until they get the picture and leave you alone. Avoid her like the plague. I'm glad that you're proud that you're a virgin. I wish that I was! It means that you're strong. I was too affected by peer pressure. Steer clear from that crowd before peer pressure starts getting to you. It happens to even the strongest of us sometimes. You ever watched the movie "Mean Girls"? lol
