Yes, I have a hard lump on my penis shaft just below the head. It's texture is rough like a scab, though other times it is less noticeable-I am unsure what the variable may be. It is circular and whitish-yellow kind of like an ulcer or cyst but it's hard and rough. In general it does not hurt, but if I irritate it by picking at it or the like, it will be somewhat painful. I've had it for several years now, but never had it looked at as I figured it might eventually go away. I am a virgin.
