So I’m 19 yo and I am pretty active sexually and masturbate my fair share! I have been tested a couple times because of other odd things that keep popping up ! About 3 days ago , a couple of dry skin spots popped up on my shaft . I tried to take a bath and even put some lotion on it to make it go away and now they dry spots are more of like raw skin . Its only on the bottom side of my penis and the top of my sack where the two meet . When I wake up though the bottom for of my tip is dry again , and I can peel the skin off. I don’t think it’s an Std but then again what do I know.
