I have small bump at the under side of the neck of penis near the head. Photo https://i.imgur.com/uewaClp.png
One year ago, one doctor prescribe gentrisone cream and I applied it for about 2 months and it still looks the same.
I saw another doctor about one year ago and he told me to leave it alone. It still looks about the same now.
It seems like sometimes it is itchy.
What is it and how to treat it? How to prevent getting more?
Thanks
