I have a 5 hour window left before the 72-hour window period for HIV PRep prophylaxis, so would be grateful for a quick answer. Sorry about the late enquiry, but I've been chasing this thing from so many avenues, I've forgotten this option till now.
I had unprotected vaginal sex with a Thai massage parlour girl in Kuala Lumpur (Malaysia) on Saturday 10 May around 4 pm (It's now Tuesday 13 May @ 11.30 am). She said she'd just arrived in Kuala Lumpur that day / just day or two before + had had all her 'tests' in Bangkok the week before which were 'clear'. Aside from the above act, I had unprotected oral sex (she on me + me on her) + protected anal sex (condom intact @ end), before finishing with the unprotected vaginal sex.
She appeared young, pretty, no needle marks on arms (but had tattoos) + I looked in her oral cavity & oropharynx & they were OK (I am a Medical Doctor myself). She was friendly, & when I asked again (again after the episode) about her health status, said she had a baby (there were minor stretch marks), so she said 'don't worry / no problem' re: her health status...
I had an HIV Rapid Test yesterday (around 48 hour mark), which was negative. I know it doesn't cover this particular episode, but makes me eligible for PRep. The local STD elderly doctor said I had a 17 % chance (based on his knowledge) to contract HIV (based on my history), & recommended PRep ! I asked him to show me his stats source, but even the CDC site he suggested to look at, quoted < 1 % risk (& that was assuming she was HIV infected). However the worry is if she was negative in her test last week in Bangkok, but had been infected in the preceding 4 weeks or more (window period for the test), she could actually be highly infectious (? now 1 - 2 % risk), in which case should I get the PRep ? I have no known STD's (but will be checking in about 4 weeks the whole lot), & no open wounds / cuts on my penis.
Thanks a lot in advance.
