This is not an HIV concern. Saliva is not infectious. Recieving oral sex is not a risk.
Fingering can't transmit the virus, this is a sexually transmitted disease and in order for that a penis has to be inserted in to a vagina or an anus, a finger is not a penis. So, there is no risk that can be associated.
Please move on from this event, testing is not recommended.
Again, I agree with mike-no. This isn't going to be a risk. Saliva inactivates the virus as does air so the only way adults get HIV is INSIDE the host or body. This is why the only risks are unprotected vaginal or anal sex or sharing IV drug needles. Otherwise, no risk. You should be free of HIV worry!
