This is really embarrassing for me, I am 13 and obviously never had sex but there are these weird bumps (not on... or in or whatever) but next to my vagina. They've been there for a while now and I live with my grandpa and I'm too self-conscious to go to him about it plus he's an old guy and that'd just be awkward. I looked it up but the things keep popping up as STD or HIV or those ones you get sexually. I have started my period if that changes anything, maybe it's hormones? They don't itch or burn or even hurt. They're just...there. I didn't think much of it but now that they've been there for a while I'm getting worried. Please help?
