question: Hello doctor, I am a 22-year-old male. Yesterday I had sex with a guy. We had protected anal sex for one to two minutes only. Apart from this, we both had oral sex. At first, we had unprotected oral sex and after that we had protected one. None of us ejaculated during the whole sex. After one day I am having sores in the penis and mouth. Now I am having a fear of getting HIV. So, I want to ask that what are the chances in the above situation of getting AIDS if my partner is HIV positive? When should I get tested for HIV if supposed I had sex today? Can I have a PCR-HIV test for now and how accurate is this?
