I've been having numerous sexual encounters, but with the same person. I was single about a month ago at which point I had explored with two other partners. However I don't believe my problem is STD's or at least hoping not. I'm certain the partner I'm with is clean. My scrotum and just below the head of the penis has become extremely dry and is loosing elasticity over the two patches it's effecting. There's not really any irritation whatsoever, although the skin has become slightly shiny. I haven't tried any medication or creams yet, I just now became worried, although it had popped up a few days ago.
