You had zero risk so don't need to test.
HIV is instantly inactivated in air and also in saliva which means it is effectively dead so it can't infect from oral. So those are 2 reasons you had zero risk. Double zero risk. So it doesn't matter even if both people were bleeding at the time it is effectively dead.
Only adult risks are unprotected penetrating vaginal or anal sex or sharing needles that you inject with.
Even with blood, lactation cuts, rashes, burns etc saliva and air do not allow inactivated virus to infect from oral. The above HIV science is 40 years old and very well established so nothing you can add will make it a risk.
