As an adult, the only risks for HIV are:
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. Oral sex, even with cuts or scrapes in the mouth, is not a risk for HIV. There is no information you could add about this event that would make it a risk for HIV.
You do not need a test since you didn't have a risk. Forget about this event and move on normally.
