I've been getting some red bumps on my labia minoras. I never got them until I started having sex, but my first was a virgin, so how could it be an std? So I get the bumps whenever I wear uncomfortable underwear (tight or unbreathable). Anyhow, they come and go. It's very painful when there's pressure (inseam of pants) on it. If I happen to wear tight pants like an id**t and the labia stays in pain for too long, the bump gets bigger and more painful. If I walk funny and keep it as comfortable as possible, it seems to heal faster. Also, if it gets really big and painful, it kinda acts like a pimple/zit. It pops and puss comes out, and then it gets smaller and heals (I know, gross). What exactly is it that I have?
