I am 28, and I have a small bump on the left side of my vagina lip
the inside. I doubt your lump
is an STD, it takes more then a couple days for one to show up... usually. I've acutally had my bump for 3 years, and I freaked out when I first noticed it, I thought it was an std. I have been to my family doctor and he said it wasn't an STD, and he tried to freeze it off, but after 2 months it came back.
