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.
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.
