I have cyst like bumps on my penis shaft with black bumps forming , anyone can tell me what it is or what should I use to treat it . I went to various doctors and they gave me wart medication which has not helped at all.

Did you go to a gyno doctor? I would go to a skin doctor, not to scare you, but if black is starting to form, that could be some sort of skin cancer. Black usually means skin dying. It could also be from the medicine. Just be safe a go to the right doctor, go to a cancer doctor or skin doctor, the cancer one would alleviate if it is or not faster. Hopefully it is something else. Did you look on line for genital warts pictures? You could compare them. Good luck and hope the best.

sparkylee22, please stop telling MEN to go to a gynecologist, or ask them if they did!

Nymets, you could have blackheads on a bad case of pimples. Please don't start worrying about cancer or dead skin, but do see a doctor. Wash with very mild unscented soap, rinse very well, and pat dry, and walk around the house naked as much as possible to dry further. Wear white cotton boxers and loose pants.
