I've noticed a lump on the skin of my penis shaft that just appeared out of nowhere. It's not painful or itchy, which is a relief, but I'm a bit worried about what it could mean. I haven't done anything that might have caused it, except maybe I masturbated about 23 days ago. Any idea what this could be? Should I be concerned?
