Hi, I’m 16 years old and about 3 months ago I discovered that the main vein/pipe(I’m not sure what it is) is darker than the normal colour of my penis. I haven’t visited the doctor but I’m kind of worried cause I asked my friends and they said that they didn’t have have a dark vein/pipe at the bottom of their penis. The vdark vein/pipe starts from the top of my foreskin all the way to the bottom of my penis. I need your help, thank you.
Any pigmentation of the genitals is a variant of the norm. Pigmentation is often absent in children, but manifests itself in adolescence. Darkening of the vein or some other area of the skin depends on the individual characteristics of the organism. By the way, many men have a dark strip from the middle of the penis to its bottom – from the head to the bottom.
Good luck to you!
