So I'm 15, I've never had sex or let anyone touch me, nor do I intend to, but I have a bump on my vagina. It's not on the outer part, it's on the inner part of the lip I guess. I got one when I was 12 or 13, but it went away after about a week or two without me doing anything to it. I'm not sure what it is, and I've heard that sometimes girls get them from shaving, but I don't normally do that, and even if I did, it couldn't be that because it's on the inner part. I don't have a mom so I can't talk to her about it, and I just would like to know what it is or could possibly be.
