Urinary Tract Cancers

White mark on Penis



A white dime size mark (big spot) has developed on the shaft of my penis. It`s white on the side and somewhat blackish from the center. It`s painless and just flat mark. I have not done any sex before, virgin but masturbates quite often without lubricants. Is it something serious?


Your condition is probably not serious, but I suggest you make an appointment with a dermatologist or urologist who should be able to examine you and provide a diagnosis and the needed course of action.
