So I am having an itch in my perineum that will itch like crazy then go away shortly after and dry out, like if nothing is wrong. I don't see any kind of redness or blemishes on the skin so it is hard to tell what exactly what it is. I have had the same thing spread to the back of my ear as well. I am sexually active or does this have something this have something to do with maybe a sweat thing. Thank you.
