>>11689This is tricky, because of how ill defined the word fetish is, so I'll start with how I define that word. A fetish, as I see it, is an all encompassing attraction to either a specific non-sexual body part (a foot fetish), a physical non-sexual object (cars, body pillows) or an extreme non-sexual behavior (leather play, bdsm.)
To qualify as a fetish, this must be the sole or primary attraction, not just something done occasionally and unnecessary for sexual pleasure. Someone who occasionally likes to rub their partner's feet doesn't have a fetish, but if the attraction is only to feet then it's a fetish.
To use your case describing a woman in lingerie housing donuts as an example, this might be considered a fetish if they absolutely must watch a fat woman gorge herself to get off and that's the primary focus of the attraction. I would consider that person to have a preference for fat women alongside some kind of stuffing fetish. However, if this person just occasionally got off to the idea of a woman stuffing herself with food, and it wasn't the primary focus, I'd say it falls under the umbrella of a general preference for fat women.
It's all up to interpretation, and I can understand arguments against what I've said, but that's how I see it.
