I have recently noticed swollen skin around the base of my penis and slightly down into the scrotum. As far as I can feel, nothing is painful. It feels puffy almost, but I have no idea how this could occur. I'm 19 with no sexual partners and exercise regularly. After an intense lower ab workout, my abs have been sore; I even felt discomfort standing fully straight up. I don't know if it is relevant, but this condition is very recent. Any help would be awesome
