Hello, your question has been answered that you did not have a risk through oral sex regardless of the length of your foreskin.
*** thread closed ***
HIV is a sexually transmitted disease. You need to use your penis to have sex and a finger is not penis. Therefore, there is no risk.
You do not get HIV from fingering. The only way adults get HIV is from unprotected vaginal or anal sex or sharing of IV drug needles. It does not matter if the anus has wounds or the finger as this is not going to be a way that someone gets HIV. No worry
Just missed another condition: if they also have wounds or sore in their anus which they don’t know either...
