Doctor,
I am 22 years old and i have a small soft pimple on the tip of penis(near opening of penis) since long. It's not causing any symptom like pain or itching. I am just worried if anything serious associated with it. I am seeing this from last few years but can't remember properly whether it was present there in my childhood. I had a fistula surgery in the month of april this year and that time, i had undergone
HIV test also which had came negative. I have attached pictures of that pimple area. Please look through it and advice me if anything to be concerned.
Thank you.
