Recently I developed a rash at the base of my penis, I assumed it was jock itch as it s been hot and I ve been sweaty. I began applying lotrimin cream and made sure to keep it well dry. I just today noticed that on the glass on my penis, the head not the rim, is slightly red and when I m erect a somewhat uniform and lumpy texture can be seen. The bumps don t hurt, itch, secrete anything, aren t discolored, and look as if they are under the skin. Any ideas?
