My penis itch only when I have to urinate. I have seen a urologist about this and he prescribed antibiotics and medicine for yeast infection. He also did a cystoscope and said he didn t see anything. I took all of the medication, however neither worked. I had sex with my girlfriend over a month ago and she got a raging yeast infection which she was treated for. I just don t know what to do at this point and definitely don t want anything jumping back and forth between us. Could this be chlamydia? There is No discharge...
