The only risks for HIV in adults are:
1) Having unprotected (no condom) penetrative anal or vaginal sex, OR
2) Sharing IV drug equipment with other IV drug users.
Your thoughts of being the first person in over FORTY YEARS to get HIV from receiving oral sex are irrational. None of your symptoms are unique to, or even indicative of, HIV infection. That is absolutely NOT how early HIV infection presents.
Look for another cause of your medical issues, because you can definitively rule out HIV.
