i have been sexually active over a year and for about six months after i would have sex the inner part of my labia or inner vaginal lips would swell up about 3 sixes the usual. sometimes it just my right side lately its both sides. I've had sex yesterday and the both inner labia swell up so much that it hung out of the vagina lips , i went to sleep and i went down almost completely except for this lower part or my labia which is about the size of a grape... it doesn't itch or burn when urine but it does hurt if i touch it, walk, or put pressure on it. i cleaned it and i was white liquid .... what is this?
