You are not having HIV symptoms. You were never exposed to HIV, so there is no opportunity for you to have symptoms of HIV.
Risks for HIV are:
1) Having unprotected, penetrative anal or vaginal sex, or
2) Sharing intravenous needles.
NOTHING else you can think of is a risk for HIV, including a handjob and protected sex. There is no detail you could add, and no "what if" question you could ask that would make this event a risk for HIV.
See a dentist for your gum and tooth problems, and you should definitely see a doctor if you are having frequent penis infections, but they are NOT related to HIV. No risk.
