You had no risk of HIV because you can't get HIV from touching or oral activities. You are so safe that you didn't even need to test.
HIV is instantly inactivated in air and also in saliva which means it is effectively dead as son as it leaves someone's body so it can't infect from touching or oral activities. It doesn't matter if you were actively bleeding or had cuts at the time either because the HIV is effectively dead.
Only adult risks are unprotected penetrating vaginal or anal sex or sharing needles that you inject with but you didn't do that so you had no risk. This sentence is all you need to know to protect yourself against HIV.
Even with blood, lactation cuts, rashes, burns etc air and saliva does not allow inactivated virus to infect from touching or oral activities. The above HIV science is 40 years old and very well established so nothing you can add will make your situation a risk.
Ya, kissing even with cuts/ even if they nibble or bite you is not going to transfer HIV. Saliva inactivates it. And air. The only way people get HIV is through having unprotected vaginal or anal sex or sharing IV drug needles.
