The only activities that could put you at risk for HIV are:
1) unprotected, penetrative anal or vaginal sex, or
2) sharing IV drug needles.
You had ZERO RISK for HIV.
No, it is NOT the same. Entering your bloodstream means getting into your circulatory system. ANY wound that does not require professional medical attention at a hospital is not a risk to you. A syringe on the end of a needle creates a vacuum environment. The blood is never exposed to air, and it is injected - again - directly into a vein.
Forget about any event that isn't sharing an intravenous needle or having unprotected intercourse. It's not a risk and never will be.
