Slut shaming

I'm a freshman in college. In high school I never had sex with guys but this semester I've had sex with 6 guys. I am not a person who regrets things usually but these situations have happened because I've been drinking too much and making bad choices. Now guys talk about me saying that I'm dirty and that you'll get a disease from me (I don't have an STD). I am changing my behavior because it's making me unhappy, but I'm wondering if I'll always have this reputation? My actions this semester are not the kind of person I want to be.
I don't think there's anything wrong with having sex with multiple partners but boys are cruel and I don't want these things to continue being said about me. I don't know what to do though.
