Hello, I have been experiencing dry, flaking, irritated skin on the top part of the shaft of my penis and right below the urethra before the glans. It has been itchy, flaky, reddish color and just recently some cracking of the skin to cause bleeding. I have been tested for herpes and chlamydia and those have come up negative. The NP I had seen also thought, because of a rash I had gotten on my back around the same time as the symptoms on my penis, it was shingles causing the dry skin on the penis. I had taken an anti-viral but to no avail on either conditions. This all began after having unprotected sex with a new partner. I am 26 years old, 155 pounds, and 6 feet.
