Perhaps you have eczema on your penis. Do you jackoff a lot, seriously? My homie wacks off a lot and he saids his dick gets chapped. Fool is a wacko. He wacks it a lot because he gets methed out sometimes.
That's why I just use sensitive-skin lotion when I wack it, so as to not put any type of fragrance or anything that can itch the dick. Sometimes it gets red though, but not chapped.
Don't wack it so hard. geez man haha
