My boyfriends seems to show symptoms of an STI. He has to go pee more often than normal (like every hour or so) and after going to see a doctor, was told there were bacteria found in his urine, though not enough to determine the exact cause apparently (small increase of white blood cells and proteins he was told). I should check myself too.
Can there be any other reasons than an STI? I am worried he cheated on me, but don't want to confront him if there could be another explanation.
