I am a 61 years old man. No sex for at least a year. I have the tingling sensation at the inside tip of my penis for the last 2 weeks. No other symptoms or visual blister, sore or whatsoever. My doctor thinks I have Urinary Tract Infection and prescribed Cipro. I am on Cipro for 12 days. The symptoms is about 50% better (it should be gone if UTI as I learned on the Internet). Can this be male yeast penis infection caused by fungus? Thank you very much.
