What should I do?

I (21 F) recently hooked up with my fwb (23 M) and in the middle of it, he grabbed his phone and started recording me performing oral. We have been seeing each other for roughly about 8 months and he’s never done this before so I was a bit taken aback but I’ve grown really uncomfortable with the idea that there is a video of me like that. What is the best way to address this? I don’t want him to feel like I’m shaming him, but he didn’t even ask so it would’ve been nice to at least have a convo about it. I’ve always been a bit nervous about sexually explicit pics and vids, I don’t even take nudes for that reason. But idk, am I just overreacting? Thoughts? Thanks!
