Swollen opening not sure if it’s normal

The opening of the penis has been "swollen" like this forever so i think its normal just wondering if anyone has the same thing. No sexual activity or infections just masturbating. It also causes no pain or anything just looks different than most i guess. Also wondering if the darkening is normal.
