I haven t been sexually active in about a year. I ve been tested for STDs with negative results... But something isn t right. About 2 months ago I got a yeast infection. I treated it, but afterwards some white/gray tissue appeared surrounding my vaginal opening that wasn t there before. My yeast infection is back, I m assuming from wearing spandex and playing ball in the heat so much, and the strange colored tissue has gotten bigger. It surrounds my vaginal opening now. It initially wasn t uncomfortable but now it is and is even painful. What the heck is going on!
