Question Intentions of Video During Sex

Backstory First: I’ve known this man for 14 years. He is a family friend. We are 10 years apart, im 23 and he’s 33 We’ve been sleeping together for 2.5 years. Honestly friends with benefits. We hang out a lot but it’s because we live next door to each other. We don’t have any intentions in getting into a relationship. I know he talks to other women but he hasn’t slept with anyone other than me since February.

Soo last night I was at his house after his kids went to bed. We ended up fucking on the couch. I was facing away from him and grabbing the table. He pulled out his phone and was like I’m gonna take a video. I was like NO you can’t. (No one knows we’re having sex) He said yes its ok it’s just for me. I was like no we cannot let something like that get out. He insisted so I said ok fine. Now I’m sitting here wondering what he wanted the video for.. I don’t wanna ask. He’s leaving tomorrow for the beach with his family and my sister is telling me that he’s going to use it to masturbate while he’s at the beach and I’m not around. I honestly have no clue what he’s gonna do with it but my mind wanders to the worst. Maybe he’ll watch it and never want to have sex again because it’s gross.. maybe he sent it to some female he talks to and made a comment about how bad the sex was to them. I have horrible self confidence and can’t get this out of my mind.
