Fattening others

I've heard of the term 'fatsexual' used before and I feel like it could apply here too.

I'm mostly attracted to women, but when men of a certain weight distribution get to a certain weight, gender doesn't really mean the same things it did before. It's really almost like they were given a sex change operation or something.

Could just be more of a lipophile (lover of fat), where you're attracted to the fat but anything else or overtly sexual isn't your cup of tea.
