Hello, I have had pain in the shaft of my penis for the past seven days. This began after inter course with my wife. There was a point where I slipped and bumped my penis against her pelvis. There is no visible bruising, no discoloration, no swelling, my penis looks normal, and I have had no functional impairment. Essentially I have a small area that is painful to the touch without any visible sign of a bruise. Is this likely to be a bruise anyway ?
