Hi all. Today I talked with HIV-infected gay guy. He told me that before meeting with his partner, whom infected him with HIV, he was negative. 3 months after the start of cohabitation he passed the analysis and determined the HIV antibody. He says, and so convincing that it is impossible not to believe that he never had unprotected sex and have never torn condom. Tell me, how can this be? It's contrary to all scientific research. If he is telling the truth, then what's the point? Please tell me, can this really to be?
