question: Hello doctor, I had protected oral and vaginal sex with a commercial sex worker two nights back. The condom was intact throughout the intercourse. When I was about to ejaculate, I withdrew my penis, and the condom was intact even then. She got up and came with tissues, and I withdrew my condom with the help of tissues. I confirmed with her twice that she does not have HIV. I am worried if I was exposed to HIV, and that she was lying. What are my chances of getting infected? I know the chances are very low, but anxiety is killing me.
