But part of my dilemma is I feel that it would be unfair of me to be with someone with the same fetishes as me because I'm not sure when and if I'd ever feel comfortable trying any of my fantasies out in real life...
I don't think you have to live this stuff out in real life to be able to enjoy it with someone else.
There is nothing wrong with just enjoying the fantasy of it, through Role Play and other such options.
I think you'll find even the simple act of eating a meal could be enough for you if with the right partner and the two of you knew what each other likes and how to push each others buttons.
You don't have to be fat to enjoy a fat fetish.
