Okay, so, i'm female, 13 years old and a virgin, but recently I started to masturbate, I wanted to see what all the fuss was about, I tried to enjoy it, but I hated it, so I stopped. But today I discovered small red bumps with white on top of them, (looks like a bunch of pimples) in my vagina. I don't know when this appeared or if it has anything to do with masturbating, but i'm scared to death about it and I feel so guilty.
