1) having unprotected, penetrative vaginal or anal sex, or
2) sharing IV drug needles with other IV drug users.
You had ZERO RISK for HIV. No one has ever been infected by being bitten or by having wounded fingers put in someone's mouth, and you will not be the first. You have a zero percent chance of being infected from this event, and there is no information or detail that you can add to this event that would make it a risk for HIV.
