I think you're fine then. I don't know if liking thin women is feasible. Feeling up a flat chest feels like doing a gyno check and Demi Moore's bare ass before she took The Substance was the scariest part of that movie for me. But my gf has all the attributes you mentioned and I don't think even frogs would call her chubby, she's just...normal. That's just what a feminine build is. It sounds like you can enjoy fucking 24-27 BMI women without fetish stuff involved and IMO that counts as "cured".
In regards to quitting fat porn I'd imagine all the usual advice for quitting regular porn should work the same - make it hard to access, go for a walk when you feel like looking at it, etc.

Curious if your relationship with the fetish matches my theory. Any formative Roald Dahl adaptions? My first time was at the same age with a woman of the same height but about 50 lbs heavier. I wouldn't have even considered someone smaller as a possibility after a decade and a half of fat girl obsession. Didn't enjoy it and assumed I had to go bigger. Took me close to a decade of unfulfilling sex to try going in the other direction.
