What disease do I have?

I am having terrible watery discharges either clear or pink-brown color, itching, sometimes burning. I went to the doctor, he took cultures. The first results came and he said I have gonorrhea and trichomoniasis, everything else was negative, including the tests for yeast infection. I told him that I have just one partner whom I have dated for a year already. We always have sex with a condom. He was surprised and repeated the tests, the results came negative. So I don't know what it could be. Did anyone have something like that?

Nobody here can diagnose you.  Only your dr can do that.
