Hello doctor,

I discovered this lesion on the penis skin. Can it be an STD? It is not painful but there is some redness but it potentially has crusted. There is no induration but it feels like a small cut. I had unprotected oral sex more than three weeks ago. Please help.



Welcome to icliniq.com.

I read your query and can understand your concern.

I have gone through the images (attachment removed to protect the patient's identity). It appears like an abrasion or due to a cut or friction.

1. Maintain hygiene. Clean the area with warm water twice daily.

2. You can apply topical antibiotic cream twice daily.

3. Avoid friction or irritation.

4. Observe the lesion. If it worsens then consult your doctor for further examination and management.

You can go for STD (sexually transmitted disease) tests now and after 3 months of exposure, if any of your partners have multiple sexual partners.

Hope this helps.

Thanks and take care.

Hello doctor,

Thank you for your reply.

So it looks more like an abrasion and does not look like an ulcer or any other STD, right?



Welcome back to icliniq.com.

I read your query and can understand your concern.

I have gone through the two additional images that you uploaded (attachment removed to protect the patient's identity). It appears like an abrasion or due to a cut or friction as of now. It is not appearing like STDs (sexually transmitted diseases) as of now. Please follow the guidelines as suggested earlier.

Hope this helps.

Thanks and take care.
