As you probably were told by your own obviously knowledgeable doctor, your negative test results show with near certainty that you weren't infected with HIV during the exposures you describe and that your symptom cannot be due to HIV. The antibody tests almost always are positive within 4-6 weeks of exposure, and always positive within 2 weeks of onset of symptoms. Further, you describe a relatively low risk exposure, regardless of bleeding bums. Your earliest symptoms at 36 hours could not have been due to HIV anyway-- too soon -- and your other symptosm don't sound particularly like HIV anyway. Repeated tonsillitis does not suggest immune deficiency.
Recheck with your doc if your symptoms persist and follow his/her advice about further diagnostic testing. The odds are good s/he knows just as much about all this as I do, probably more. (I actually provide personal care to very few patients with suspected early HIV infection; your doc probably does it all the time.) Or if uncertain about his/her expertise, visit the excellent Sydney Sexual Health Centre. It is one of the world's premier STD/HIV clinics.
Bottom line: Relax. Putting together all the evidence and probabilities, your chance of having HIV is zero or close to it.

Here in Boston at the Fenway, they tell me oral without ejaculation is VERY, very low risk. They also follow your advice Dr. H. - ask status and STD status before you suck - some people lie and some people don't, but a good portion will give you an honest answer....and of course use condoms always for anal! If you follow these rules and NEVER stray from it - you will be fine and dandy...his words not mine!
