It's clear, based on your inability to accept that you had no risk, that the issue is psychological in nature. Whether it's shame or guilt or something of that nature over what you've done that is the root cause of all of your problems, you owe it to yourself to seek out a therapist with whom to discuss this problem. Until and unless you take control of your mental issue around this whole situation, you're not going to be able to put it behind you. Stop wasting your time asking questions about a disease that has nothing to do with your situation and Google for mental health support in your area to get the kind of help that you actually need.
"Exactly, I don't have medical training ..." "I have searched everywhere for a case similar to mine and I can not find one at all""I am the only one on the entire planet with this kind of risk."
For starters, there is no risk, but you are the only one on the planet who thinks it is a risk, which is why your endless search for another person is a waste of time. See a therapist and find a new doc who deals in a reality based world instead of the one who gave you PEP to get you out of his office.
This answers all of your HIV questions, and if you can think of any more just reread about the 3. You had zero risk therefore testing is irrelevant to your situation because you had zero risk. HIV is a fragile virus, which is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from touching, external rubbing or oral activities. It doesn't matter if you and they were actively bleeding or had cuts at the time either because the HIV is effectively dead.
Only 3 adult risks are the following:
1. unprotected penetrating vaginal with a penis
2. unprotected penetrating anal sex with a penis
3. sharing needles that you inject with.
The only way to get HIV is if you did one of the 3. The situation you describe is a long way from any of these 3.
Even with blood, lactation, cuts, rashes, burns, etc the air or the saliva does not allow inactivated virus to infect from touching, external rubbing or oral activities. Doctors have calculated the risk from what you describe to be less than that of being hit by a meteor, therefore no one will get HIV from what you did in the next 40 years of your life either. The above HIV science is 40 years old and very well established, so no detail that you can add to your encounter will change it from zero risk.
If you didn't have one of the 3 then you are just worrying about your own hiv theory - which is unrealistic for you to think that can become reality - so you should move on back to your happy life instead.
You should stop taking PEP. It sounds like the Er gave you the PEP to get rid of you - were you very anxious and demanding PEP?
If it didnt have a needle and liquid went In or touched your anus then why would there be any risk? HIV dies when it touches the air. You would have a risk If the syringe had a needle and he poked you with it if it had been used recently and was contaminated with blood that Came from an HIV positive person, but you stated you didnt. "Fingering" brings no risk. What you should be worried about is being around people who use those types of drugs and have sex while under the influence, they will bring you a lot of problems.
