Somebody pls help! I’m desperate!!

I’ve had burning in my vagina for over a year. I’m dry. I have cuts in my vagina. It burns to have sex then burns to pee afterwards. When I wipe after peeing, it burns. To spread my lips or move them around to shave everywhere it burns to touch!! Everything burns. Thought it was BV but the test was negative. I’ve been tested for everything and it was negative. I’ve tried boric acid suppositories I’ve tried steroid cream and estrogen cream. I don’t use any soap anymore. Nothing changed for this to happen. Nothing. I haven’t changed detergents or soap I even tried cotton underwear. I’m tired of being in pain to have sex!!! Help!!!
