I had dry skin on my penis for a while caused by friction. This eventully disappeared after about a month of weeks of care and moisturising. However, a small red rash still appears around the top of my foreskin near the opening when friction is applies to my penis, and when urine splashes onto it whilst the skin is cold. I have no other symptoms, but am slightly worried as this won't go away. It is not painful or itchy or dry, it just someitmes appears when one of these two things happen. Anyone know what this could be? Help is greatly appreciated, thanks in advance!!
