What is this?

I'm sorry I hate to be that person who makes posts about rashes and shit, but I'm not close to my family members and we don't have a whole lot of money so I don't want to make my mom pay money for something that might be harmless. Anyway I have this itching around my clit area and there are some bumps that if I put pressure on sting. I don't have sex with anyone and never have done anything, even kiss, but I do masterbate and touch myself down there quite often. Please help.
