I have developed a red, 0.5 inch oval-shaped
patch of skin on the dorsal head of my penis (pics). The red patch has persisted for more than 7 days without changing and without me disturbing it. It is mostly smooth, slightly red, the skin appears shiny with a different texture than surrounding skin. There appears to be a border around the area where the redness is more pronounced. No itching, no burning, no discharge, no pain.
