Dear Sir

What is the probability of getting the HIV infection from the oral sex I had oral sex with the call girl and I do not know her status but she was healthy and beautiful . she had oral sex on me for 2 mintus then mastrabuted .

I belive her mouth was clean and I had the VDRL test after a week time it came negative . My question . Do you advise me to go for HIV Test such as HIV DNA PCR test or something else to find the infection quekly or hold on for 3 months to go for antibody test . I am little bit worried
