I enjoy the company of a chubby woman, but don't want her to know that's why I'm interested in her, how do I avoid being called a chub-fetishist?

That's what I had typed up before the character limit got in the way. So yeah, I like chubby women, it's a preference of mine. I could be called a chub-fetishist because it's what I find most physically attractive. Some of them may have negative opinions of chub-fetishism and I don't want them to think I only like them for being chubby, even if that's true. ***How do I approach this?***
