sex videos

So my “friend with benefits” and I were having sex and i saw him grab his phone and lay it on the bed and didn’t say anything . I look back a few seconds later and he’s videoing pretty up close to what’s going on. However, I didn’t tell him to stop or delete it because I didn’t wanna cause any drama. You can’t tell it’s me or even my room. I feel kinda violated now but feel like i can’t say anything because i didn’t stop him when it happened. Any ideas on how to approach it? Or should I just leave it alone?
