Hi doctor i am 22, I visit a surgeon doctor yesterday about my problem , but i guess i need to consult more doctors, the problem i have is with my penis ... i have got pigmented lesion (like a pimple kinda thing) on the tip of my penis near the place i urinate ( AS PER THE DDCTOR SAID TO ME) - its color is close to gray and i feel its due to masturbation! It has no pain , no itching nothing but i am worried about it. The size is very small about 1-2mm. I would be really glad if you could help me with this.
