Hi, Ive had a painless rash on the head of my penis for the last 4 weeks. Sometimes its a bit itchy, but mostly it just comes and goes. It disappears for a while and then reappears. I had unprotected sex about 6 weeks ago, and Im worried it might be an STD. Could this rash be a sign of one, or is it something else? What should I do next?

It is recommended to get tested for STDs to rule out any infections. In the meantime, you can use an antifungal cream like Clotrimazole 1% twice a day on the affected area for 2 weeks. If the symptoms persist or worsen, please follow up with a healthcare provider for further evaluation and management.
