Hi my vagina is red on the outside and sometimes itchy and only when I am done scratching it does it then like burn a little with like heat almost. Now the redness is going away and not really itchy but it is now really dry with like a dry skin appearance ( like flacky). I have had this before and just tried to not wear underwear when I could and it went away now it is back like 1-2 months later. What is this? And what can I do about it? It s only the outer part of my vagina-the whole outline-top,sides and a little in back
