I have a question. If individual incidents of condom protected sex are zero risk, and don't warrant testing, then why is the advice on this forum to test every year, if one has more than two sexual partners? Surely if it is truly "zero risk" then zero times a hundred is still zero.
I can think of only two possible reasons
1. "Zero" risk is not in fact zero, but something very small. Therefore a very small risk multiplied by a hundred equals a significant risk; therefore testing is warranted
2. It is assumed that people are too dumb/drugged/drunk to know if sex was truly protected or not.
? which is it
