[|Human|] I have had a small movable lump under the skin of my penis, left side, under the forehead, for a year or two! It  It is there whether i have an erection or not and is ticklish. I now wonder what to do about it! Is it harmful and should be removed? Is it what is referred to as sebaceous cyst?!
