Three condoms? ya, whomever tells you things like that is necessary (including your own anxiety) has it all wrong. One condom is plenty. The ONLY risks for HIV are to have unprotected vaginal or anal sex. Or to share IV needles to inject drugs. Air and saliva inactivate the virus. A hand job won't result in HIV. Condom protected sex will not result in hiv. You had no risk from the events. Whatever you see on your body is unrelated. You don't need to get tested for HIV. There is no reason with no risk.
From now on, just use 1 condom because friction can make 2 or 3 break themselves.
You can't get hiv when you used a condom and the FSW knew that - now that you also know that it is time to move on instead of wasting your time studying your body then making up an idea that you caught hiv which would be impossible. You are fixating on hiv, then thinking you are proving you got it - your thinking is like having a brain cancer fixation then imagining those spots prove you got brain cancer from the FSW encounter.
