70 days ago, I engaged in risky sexual behavior and am now extremely worried I may have HIV. It was with a transsexual prostitute (yes, I am an idiot). "She" topped me with a condom on and ejaculated onto the surface of my anus. I wiped the semen off with a tissue immediately. I am worried that this semen (with a high probability of being infected with HIV) came in contact with the mucosal membranes in my anus.
2 weeks later, joint soreness and lethargy. No coughing, sore throat or fever to speak of. This lasted about 3 weeks until I had sex with someone else that had a cold, and I got what she had, which lasted about a week. I also have a rash above my left ankle that presented maybe 3-4 weeks after the incident and has not gone away. (I suppose a good sign since it is not on my trunk and did not last only 2 weeks).
I am going to get tested at the 90 day mark, but in the meantime, I was wondering how likely it is that HIV was transmitted in the way aforementioned?
Additional note: there probably wasn't any injury to my anus from the sex itself, as the escort had a small penis and what I'm used to putting up there is much larger.
