Do you have a student health clinic that you can go to for free? I strongly recommend you go there for two reasons. First, you will want to get a for-sure diagnosis from a doctor. Since this is something you will need to tell all your future sexual partners about, you want to be sure that's what it is. Second, if it's only a few warts, they can freeze them off for you right there. It's a lot quicker, some people think it's less painful (the Aldara cream takes weeks to work, which means weeks of chafing), and it's a lot safer than buying a prescription from someone you don't know off the internet. If you still want the cream, they may have free samples in the student health clinic.
