Welcome to the forum.
From your description, you had entirely safe sex. However, you were playing with fire for having sex, especially anal sex, with a known HIV positive person. Condoms do break sometimes, you know! Did you also ask him whether he is on treatment for HIV? If not, you should do so now; if he is taking anti-HIV drugs, the chance of transmission is markedly lower than otherwise. (Click on the information about it on Today's Pulse at the upper right of this web page.) Still, in the future I suggest you ask about HIV status before having sex with anyone and not go ahead with sex with those who are positive, don't know, or seem evasive about it -- or at least avoid anal sex with such persons.
To your specific questions.
1,2) Having said that, oral sex carries little or no risk. The important thing is that condoms were used for anal sex and did not rupture.
3) Urine and saliva are generally not infectious for HIV. Both fluids inactivate the virus.
4,5) I would not recommend PEP and I would not do it if I were in your situation. However, guidelines for PEP are quite variable, and some experts might disagree. You might want to check with a local clinic or physician who is familiar with local guidelines.
6) You apparently have HIV testing routinely from time to time. That remains a good policy. From a strictly medical or risk assessment perspective, I see no need for testing on account of this exposure. But since you are worried, you probably should do it. My guess is a negative test result would reassure you more than my words can do.
Good luck-- HHH, MD
The escort was on treatment - Atripla - with high CD4 counts and an undetectable viral load. Does this make a difference?
That makes transmission very unlikely. Did you read the news blog about it? You definitely don't need testing or PEP.
I did read the blog - very good news.
Thank you for your help.
I wonder if I could ask one more quick question then I'll shut up. Around two weeks after this exposure I started getting some mouth ulcers, no other obvious symptoms - is this worrisome or suggestive of ars? I'm thinking in the possible event that there was an unnoticed condom breakage this could be ars manifesting?
Mouth ulcers alone, without other symptoms, are not worrisome with respect to ARS. But if you remain concerned, see doctor or clinic.
