Good Day All

2 weeks ago I had protected sex with a stripper in a Strip club (Stupid I know)
However, after I was done She removed the condom with a napkin. With the same napkin she gripped my penis to wipe off the residue, however in doing this I believe I've been infected with an std(via condom in napkin). 4 days later I have an irritation in my urethra after urination and also during other parts of the day. I've been to a clinic, and now have to wait at least 7 days for my results. can anyone shed some light on this situation. am I being reasonable considering the circumstances? is HIV Transmission also a possibility?

Sorry if I'm cross posting but because of the irritation I am fearing the worst possible scenario for myself, any professional opinions? :-(
