HIV rash

[salvonastasi]

2 days after possible exposure I got an itch-less rash on both of my legs. There is no agreement on the various sources I looked at about within how many days a rash can appear. A source says acute rash can appear within few days. Another thing that worries me very much is that one of the picture I saw on the internet about the maculopalpular rash (which says is the rash associated with HIV infection) looks exactly like the one I have got. There is no other condition, but it's just 4 days into the likely infection.
I know you will say is very unlikely also given the fact that the sex was protected, it was a very short vaginal penetration and, as far as I could tell, the condom didn't break up. I touched the genitals of the SUB-SAHARIAN PROSTITUTE i had sex with, which is another great cause of worry, infection-wise.
But then, how to explain the rash, just after the sex with the prostitute? it was protected, yes, but is protected sex 100% sure?
I would be happy if you could explain me more about the possible causes of this rash, a phenomenon which had never occurred to me before, in my whole life.
I am particularly worried because before noticing the rash I had unprotected sex with my regular partner.
Please help.

You never had an exposure.

If you had protected sex you did not have a risk and do not need testing. I can't tell you what the rash is because there are THOUSANDS of causes for rashes. It is way to soon to have anything to do with hiv.
