I am 14, never had oral sex or any kind of sex, although I do masturbate, and found three bumps on my vagina. Two are tiny and skin coloured, and one is huge and red-ish. I tried popping the huge and red-ish one, and a bit of puss came out, but it's still there and i don't know what it is. It feels big and deep, like I can feel that some of it seems to be under the skin??? How do I treat this and why are they there??? Also, can this be from sitting on public toilets??
