I have had this bump on my penis for quite some time now but it in no way causes any discomfort. At first I thought it was a skin tab so I tried to stop the blood flow to it so it would "Fall off" and it helped but it came back and its a little bit bigger now. Here are some pictures. If anyone has any idea what it might be please do share. Im just more concerned now because Im going to start getting into a physical relationship and Its quite embarrassing and I dont want to spread anything to anyone.
