I've had a rash since I was about 5 yes old ( I'm now 30)...the rash used to be on my waist line in the front but in the last 8 years it moved to my inner thighs. It doesn't hurt or itch much. It's unsightly ( small to med red dots with a few slightly raised) is it possible this is an STD that was somehow passed to me before becoming sex active ? Also when I sweat and when I get out of the shower it seems to go from a pale red to red as if the water or moisture I'd affecting it. I've been petrified to ask anyone about this for fear of bad news. It's been my demon. I just wanna be normal. Any clue what this is?
