The only risks for HIV in adults are:
1) Having unprotected anal or vaginal sex, or
2) sharing intravenous needles with IV drug users.
HIV doesn't enter the body through the shaft of your penis, even with cuts or scrapes. HIV enters through the urethra, which only happens if the head of your penis is not covered by a condom during intercourse. Receiving oral sex isn't a risk for HIV at all - it's not transmitted via saliva, and no one has ever been infected that way.
Whatever is causing your medical issues is not related to HIV, since you were never exposed to HIV.
