My partners porn preferences - advice

Hoping this reaches the right audience- this is my first ever reddit post and I’m honestly not too sure how to even use this app. I posted this on another community page and unsure if that’s even a thing (to post on multiple communities). Just looking for quick advice / answers.

Essentially, on multiple occasions, I’ve discovered my partners porn tabs. Majority of it being Japanese girls with “big tits”.

Few things I’d like to preface/add here:

1. I’m not Japanese, I’m Latina
2. I do not have boobs nearly as big as the ones I see on his tabs/search history
3. I’ve expressed to him how I’m uncomfortable with him watching porn let alone confronted him about his fetish for Asian women (specifically Japanese girls) which he has constantly defended and “reassured” me that it doesn’t mean anything to him and that I’m his type, its mere coincidence that what I’ve seen on his phone has been Asian women because he watches “all different genres and doesn’t have a pretence”, etcetc
4. He has been with plenty of Asian women previously, the one before me being a local Japanese woman whilst he was on a holiday there.

He will often play with my boobs during sex and make me put them together (to appear bigger I’d say?), give him a boob job, and has made comments which I’ve expressed made me uncomfortable about me using certain products or whatever to naturally grow/enhance my boobs. He’s reassured me “I’m perfect the way I am” but after this, I honestly feel so sick and betrayed?

Thoughts?! Am I crazy? Am I valid??

(Honestly, it’s late at night and this feels very weird/wrong even writing this post because it’s such a real/raw/personal dilemma I’m having.)
