Hi, I have a small soft brown lump the size of a pea underneath the head of my penis on the shaft. Its on the underside of my penis and does not cause any pain what so ever. I've had it ever since I can remember and I didn't really think of it until now. It has not changed size, shape, color, or anything. Its just been there for pretty much my whole life. If you could help me out and give me an idea on what it is, and if it is removable, that would be great , thanks
