I have irritation/redness just on the inside of the tip of the penis. Slight discomfort (feels like chafing). No Itching burning during urination. No bumps or rash on the penis or testicles. I noticed over the past week or so I seem to have a need to urinate more frequently and the urine seems to had a slight odor. I had sex about a week or so ago but I used a condom and was very safe. Does this sound like a UTI or a STD? Ive never had either one before.
