Hi Doctors, I hope you're well. I recently had 2 incidents where I visited Korean CSWs based in the bay area and things got hot and heavy and I ended up having unprotected vaginal sex both times (2 different CSWs) They both work for the same org. I spoke to the operator of the org and she told me the girls get tested on a monthly basis and also sees the gynecologist on a monthly basis and that the girls are clean. Both incidents lasted for about 1-2 minutes. Afterwards I felt anxiety and worry, but I read the answers archives and I came to the conclusion that this is a low risk event and my chances of catching HIV is 1 in 1200 roughly (I am uncircumcised) and the chances of CSWs having HIV is about less than 1 in a thousand, which puts my overall risk at about 1 in 1.2 million (per Perplexity). 

Welcome back to the forum.  Thanks for your continuing confidence in our service. The statistics that you mentioned are on target and I agree with your assessment. These were very low risk encounters.  At five weeks a fourth generation combination HIV antigen/antibody test would detect over 99% of recent infections. Neither of us has ever seen or heard of a person with a negative test at four weeks or beyond who went on to become HIV positive. It does apparently occur, but is very, very rare.  ---
