I'm not sure why you are reasking your question. You were already told you had no risk for HIV. One more time. The only risks for HIV are to have unprotected vaginal or anal sex (without condom, requiring penetration) and sharing IV needles to INJECT drugs. Those are the ONLY risks. Air and saliva inactivate HIV. Fingering is NOT a risk. So, if you had no risk, you can't get HIV from your risk. Right? Think about that. And fevers happen with all sorts of every day things. Not a big deal.
Your anxiety is over the top. I would suggest you look at that as the disorder you need to treat. Asking for reassurance and looking things up and giving into your anxious, intrusive thoughts only makes it worse. So, try to work on the anxiety to get over this.
