Hello i have noticed an extra wrinkly area on the right side of my penis below the head. I think it comes from over masturbation without lube but i am not sure. It does not appear when my penis is erect and i have been moisturizing the area lately but it has not gone away. It kind of looks like wrinkly small bumps on the skin and it really stands out. When I stretch the area, it disappears and looks normal. Someone please help me. I dont know what it could be and im really hoping its not a disease.
