I've read a few other threads on here that attempted to address this but not much information was given. In the Far East, where I live, Subtype E is prevalent and multiple studies have shown that it is transmitted easier via heterosexual sex. It also affects Langerhans cells, which I suppose would mean that HIV fluid contact with glandular areas would increase risk (http://gateway.nlm.nih.gov/MeetingAbstracts/ma?f=102217906.html).
I had protected intercourse with a sex worker in Malaysia. It seemed that she was used to customers not wearing a condom and I had to bring my own. After sex, I removed the condom and began to masturbate myself on her. I believe her fluids were on the base of my penis, so while I masturbated I transferred these fluids to my urethra. Since the fluids were in a warm, moist environment and were transferred to my urethra mere seconds after penetration stopped, I think I could have easily put HIV fluids in my urethra and contracted Subtype E this way.
Exactly two weeks after exposure, I developed a rash on my trunk and back that is completely consistent with every description of "ARS rash" I have read online. I know that symptoms cannot diagnose ARS, but this seems to cement my belief that I have contracted HIV.
It has been 2 and a half weeks since exposure. If I get a test now, will it mean anything? How long should I wait? I have read some posts claiming that Subtype E takes longer to detect.
I know there are many "worried well" people on this site, so after seeing so many silly worries, it's easy for people on here to expect everything to be a false alarm. Indeed, in the West, my exposure would basically pose no risk at all. I fear the risk for my specific exposure is different in Asia. I expect a positive test result.
