I recently noticed a ring (kind of like ringworm) that is on the head of my penis. also on the shaft, up near the head, there are two or three red bumps that have itched before but arent consistently itchy. They re just kind of there and are sometimes very visible, sometimes faded away. The first time noticed was while having intercourse With my girlfriend. It felt like I was itching the red bumps on shaft while thrusting. Since then they haven t swollen up, but are still just marks on me
