Fat Fetish v Being Dominated

My (F26) partner (M28) has a fat fetish. I entertained it for a bit, but as someone with a history of EDs it got too much and I had to stop a lot of the stuff happening during sex (names (fat body, so jiggly etc.), grabbing my ‘fat’, and the rest…). Today I was on pornhub and came across the exact kind of man I like – a bit thuggy/chavvy, talking you through it (“cum on my dick”, “good girl”, “just like that baby”), lovingly dominating, bit of choking. How do I bring this up? Do I show him the video? When we’re having sex he doesn’t even look at my face, it’s all eyes on my stomach. He rarely speaks besides calling me a ‘goddess’ which is typically used in the FF community. I was thinking of doing a little drinking sex question game where I can bring it up in a relaxed setting? Advice please 😫
