Dermatology Questions? Ask an Online Dermatologist.
Hi and thanks for the query.
Do you have a recent history of unprotected sexual contact with anyone of unknown STD status?
How long have you had the sore for?
Is the pain sharp and tingling?
Can you attach a picture?
Fungal lesions are characteristically itchy and develop a white crust around them, they are not painful.
An open sore on the penis which stings or develops a sharp pain is a characteristic of herpes sore.
The best way however, to evaluate a herpetic lesion is by visual analysis, since I have not seen the lesion, it is difficult to determine its etiology correctly. The symptoms you exhibit are of a herpetic lesion. The best course of action will be to see your PCP for an examination and a more thorough evaluation.
I would suggest that you apply Fucidic acid + hydrocortisone ointment on the lesion available OTC for the time being to prevent secondary bacterial infection on the sore.

Thanks for the picture.
These do look like herpetic lesions.
You should see your PCP for further evaluation and confirmation of the diagnosis.
With these lesions 100 percent certainty can only be achieved when one has examined the lesion and tested it. Tests are cell culture and a PCR blood test.
That is why I have suggested that you see your PCP.
