About a month or so ago I noticed a dark purplish vein on my penis. I am uncircumcised. It only hurts a bit after having masturbated. Other than that, its okay. I am only 16 and am afraid to tell my parents about this. Do I need to see a doctor? Is it serious? The vein is about 1.5 cm big and is purple in color. There is also a little purple spot near that vein also. I am terrified by this. Please reply asap! I heard that if its a bursted vein it can take a while to heal.
