Hi guys, I am 19 y/o and has had 2 sexual intercourse, the last being about 2 months ago. Recently, I noticed that I have a bump on the skin of my penis. The exact location of this bump is almost at the bottom of the shaft and a little to the side. It is on the skin of the shaft and not actually on the shaft. The size of this bump is just a tiny bit bigger than the size of the ingrown hair bumps on the penis. The bump also has like a dark brown dot, and is the same color as my skin. At first, the bump was painless, so I got curious and started to press gently on it, then it becomes a little painful.
Can someone please tell me what it is?
