Share the reports. And where exactly is the pain? Is it with urination?

It sounds like you’re experiencing intermittent, brief stinging pain at the tip of the penis. Since your STD tests and urine culture are normal, the discomfort could be due to mild irritation, sensitivity, or a non-infectious cause like dehydration, concentrated urine, or minor urethral irritation. Try increasing your water intake, avoiding spicy foods and caffeine, and maintaining good hygiene. If the pain persists or worsens, consider seeing a doctor for further evaluation, including a check for mild inflammation, prostatitis, or nerve-related issues.
