if someone had 50, or 500, episodes of protected sex with sex workers in the US (in all cases, vaginal or anal sex WITH condom, and condom did not break), in a 1 year period, with lots of unprotected oral sex, are the risks of hiv still basically nil?
i understand that sex once with a female sex worker that is protected is basically riskless as long as condom did not break, but how about with 500 episodes?
i assume it would be the same?
