i have these 4 bumps near the top of my vagina. I have had them for a while, sometimes they're noticeable and other times they're not. i have been tested twice for all stds and came back negative. i dont have it anywhere else. I'm thinking maybe shaving, because im lousy at it. Then i sweat down there often, so my skin is being wonky. idk what it is. its just these 4. 
they don’t itch, blister, burn. they’re typically skin colored, hence why i don’t notice them unless really examining.
if your tests came back negative then your fine. its probably just bumps of after shaving. you may have cut yourself with the razor if pushing to hard against your skin.
