i have a rash that goes all the way around my penis like right before the head and like a small part looks like its peeling or cut. it doesnt bother me too much, and it looks like lil red bumps but tiny ones and this is only at the top of my shaft. i have been working out alot for the past couple of weeks and i sweat alot. i am also 5′ 7 225 pounds so i dont know if it is from the sweat or if its irritation from jogging or what. anyone have any answers? oh and i dont sleep around so i dont think its a std.
