Lately I've been getting these weird lumps about the size of a pea in my vaginal area that have been coming and going for about 6 months now. I don't know what they could be, they are basically painless except they feel like they are pinching sometimes. They are mainly skin colored and other times they might turn to a bruising color and rarely reddish. They are mostly under the skin except this one that i found under the hood which bulged out a little but later bled and went away on its own. I've found that it might be an ingrown hair or something but I'm not sure that's it even though I do shave sometimes. They usually go away after a few weeks and only come one at a time, and I've looked up bunches of things to try and find out what this could be but I am still unsure. And whenever I actually get into the doctors they've gone away by then. I have only had unprotected sex once with another virgin who hadn't had any sexual contact whatsoever before. Could this be an STD??? Please help!!
