What Causes Itching Sensation In Penis Despite Taking Ciprofloxacin For UTI In Men?

Hi my name is Ronnell and I went to the clinic and was diagnosed with male uti, and I was given ciprofloxacin for the problem. After about 3 days of taking the prescription the pain is gone when I urinate, but itches a little when I finish urinating. I also masturbated and I was itching inside my penis as if I wanted to stick something long and small in my penis to scratch the itchiness. The semen was yellowish like, and I think it was due to the prescription. I never had any itchy sensation inside my penis when I m urinating or masturbating, so is this the side effect from taking ciprofloxacin, or is there any other prescriptions for this symptoms. I m still taking the prescription of ciprofloxacin.
