Sexual disease

I've had protected sex, nearly 3 months ago, and still suffer from symptoms such as redness and itchiness of penis. no bacteria was found at that moment, neither in urethra or urine. What would you recommend me to do, to sanitize this??

They did not, but I don’t have discharge, just redness and itchiness.
