I have stain on my under wear ant im not sure if i have a uti can i show picture please?

Not on the free HealthTap platform. A picture will not be enough, see your primary care doc if having symptoms. Alternatively you can use the paid portion of Health Tap if so desired.

If the underwear stain is coming from your penis, most likely it means urethritis, which in turn usually is due to STDs like gonorrhea, chlamydia, or nongonococcal urethritis (NGU). Prostate infection and similar conditions also are possible, although UTI itself doesn't usually cause discharge. See a doctor for in person evaluation. Good luck.

If you do not have any other associated symptoms such as frequency, pain with voiding, etc. I would recommend observation for now. If you are at risk of sexual transmitted disease with a recent exposure and stain persists next day or if you have new symptoms then see your doctor for testing. Picture can't be posted in this forum, sorry. Take care and good luck!
