I am 220 lbs. 5'8'' and 21 years old. I have a reoccurring problem. There is a ball (anywhere from a pea to a small grape) under the skin of my labia minora. It's up by the clitoris. The first time I got it I was trying to pop it. Left it alone for a few days and it wouldn't go away. i tried again and this time it popped. Blood and pus came out. It was gone after two. A few weeks later its back but this time doesn't feel pop-able. Its tender, but it may be because I'm always checking on it. It gets a little bigger after sex. It's bothering me a lot. I've been tested for std's recently so I don't think that is it, but I won't rule anything out.
