Hi, thanks for your question.
Urinary tract infections (UTIs) are not usually caused by sexually transmitted infections (STIs). They both affect the genitals, but they are caused by different bacteria/viruses and need different treatment.
Trichomonas is a rare STI. Men are not typically screened for it because of this reason. If your other STI test results are negative I would consider that conclusive.
Also the sexual contact you’ve described is not likely to pass an STI or Trichomonas.
It sounds like you’re having symptoms of a UTI. I would recommend going to your doctor or a walk-in clinic and getting testing (urine culture) and treatment for a UTI. Although UTIs are less common in men than women, they can still happen. It’s important to treat a UTI with antibiotics so that it does not spread to the kidneys.
