So I am a happily married straight man, but for some reason made the stupid choice of hiring an escort in Northern Mexico.
Before we began we brushed out teeth (no flossing, just brushed).
We enganged in mostly unprotected oral sex, from her to me. About 5 minutes of unprotected oral sex from me to her (only her clitoris) and finally protected vaginal sex during which she peed on my pelvis and a very brief unsuccessful attempt to anal sex (like 30 seconds or so).
After we finished, we showered individually, even using diferent soap bars and towels. I checked with water the condom we used for vaginal and anal and it didn't break.
About 8 - 9 days after this I developed a light fever 99.32 F (37.4 C) which lasted about 10 or 12 hours, the fever came with a light headache (which was more light dizziness than an actual headache). Today, day 13 the fever has not returned since it went away, but this light headache/dizziness thing keeps bugging me. No other symptoms have occurred.
I know my exposure is considered low risk and that the likeliness of a sex worker to be infected is relatively low (in Mexico the prevalence of HIV in Female Sex Workers is 0.6%) and also that the only way to know if I am infected or not is through testing at 4 weeks and retesting at 3 months, but still I wanted some serious opinions on whether or not you think I should be concerned.
I have considered getting tested by PCR so I don't have to wait the entire window period, but I've heard that PCR can produce false positives, so that scares me a little.
Thanks in advance, I know you've probably seen this question a million times.
