I have oral sex with my partner for 40days ago(without a cum, and I am gay. I used condom for anal sex). Since then, I had a sore throat and went to the hospital to take antibiotic pills. But It didn t really work well, so I got Sexually Transmitted Disease PCR for my throat by taking sample from my mouth and spits. It turned out that I carry Gardrenella vaginallis. Is it the real cause of my sore throat? or should I take more PCR? (STD PCR includes Chlamydia, gonorrhoea, Ureaplsma, Mycoplasma, Candida, trichomonas, and syphillis)
