For the past few of months I've had this bump, almost more of a line of rough skin running parallel with the bottom of the head of my penis. I originally thought it was just dry skin due to friction, and maybe it is, but trying different moisturizers, vaseline, etc have not cleared it up. Nor has abstaining from sex/masturbation over stretches of time. I've never had unprotected intercourse which makes me think it is not an STD. It also seems like there is a bit of a lack of pigmentation near the area, but not sure.
I have an appointment with a dermatologist in a few weeks and was going to get his advice, but in the meantime I am trying to determine what this could possibly be because it has become disconcerting. It does not itch and is not painful, but any friction is just annoying to the touch.
