Is it okay if my BF wants to keep an X vid of us?

This post is purely for advice. Im 26F, BF is younger than me but of legal age. He wanted to keep a X video of us coz he find it weird and he felt like he’s cheating whenever he msturbtes and watches other people’s X vid. One time he sneaked a cam while we are doing the thing but eventually turned in the vid coz he was so guilty and he could not dare to betray me. I don’t know how to react. This is my first time.

I badly need an advice if this is a red or a green flag.
