Finger in Anus

I'm male, gay and I recently had an exposure with another man whom I don't know at a bar.

It was not a sexual intercourse, just fingering.

He inserted his finger in my anus for one time, and I noticed he had cut on his finger with some blood on it so I told him to stop. Still his finger was inside my anus for few seconds before I told him to stop.

Assuming he has HIV is it possible for me to contract it this way?

No, you weren't ever at risk of contracting HIV by fingering. Nicks or no nicks.
