question: Last night I noticed a small red patch on the shaft of my penis and a small bump barely 2x2 mm. Its been 5 days since I last had sex which was protected. The red mark is slightly irritating though I think it might just be due to my own periodic self examinations. The surface around the bump is sometimes shiny as if moist. The seems no bigger then a nodule for a hair but I can see any hair coming from it and Im not sure if its an ingrown or not.
