Dermatology Questions? Ask an Online Dermatologist.
Thank you for your question. My name is***** and I will do my best to provide a useful input.
Would a photograph of the affected area be possible at your convenience?
Thank you for the photograph. To me this just looks like a penile cut with some central hemorrhagic crusting which is causing the appearance of a bump. Cuts like this can occur when masturbating with dry penile skin, so using lubrication such as KY jelly or baby oil is helpful. Already having a cut and masturbating can make it bleed which can dry up as a darkish bump. No cause for alarm. Just apply Bacitracin ointment twice a day on the affected area and do not masturbate or have sex for the next week to give the penile skin a chance to recover. Nothing further is required.
You can buy Bacitracin ointment over the counter without a prescription.
Please feel free to ask if you have any queries. I will be happy to continue further and do everything I can to provide you with the service you seek.
