I noticed this spot on the head of my penis today, which came out of the blue. It is the only one that I have, it causes no pain, no itching, no discomfort whatsoever. It does not feel firm or out of the ordinary (it feels like the rest of the head). I have been with the same sexual partner for 4 years, and we have been each others only partners. I know with how I described it, it may seem like something minor, but I’m still a bit worried about what I should do. I have tried to Google every possible combination of words to find something similar, but I’ve gotten nothing close enough to satisfy me with an answer. If anyone has any idea of what this is and if it is serious or not, I would appreciate the response.
