As a hypnotist who helps people find themselves through fantasy fulfillment, I've seen a good number of people come to Me convinced they were just a feeder (I've even had a person come to Me as an out-and-out fatphobe), and over time they discover (without My pushing, obviously), that beneath it all, they really just... want to be "that fat woman" *themselves*.
What are your thoughts on feeders who discover that they're actually gender-queered feedees themselves?
i have been a part of various kink communities over the decades, and i would agree with your assessment - compared to others, feedism has a higher degree of masc-identifiying participants transitioning to something else. either gender-fluid, or transitioning (either in reality or in their fantasies) into the bbw that they idealized.
i guess i have experienced it personally, to a degree. while i have no intent of transitioning, as i grew from a fit feeder to a ssbhm feedee, gender play definitely became a part of my sex life with my partner. soft, fat flesh definitely leans to being more feminine than taught, lean muscle (i know some bhm will bristle at this, lol). pecs turn to boobs, all of that... when my partner shaved off my body hair, it became even more apparent the growing (pun intended) similarities between my fat body and bbw partners i'd had in the past... and that was a turn-on for both me and my partner.
my theory is that it is all related to the deeply-programmed societal relationship of soft voluptuousness being seen as feminine.... and as these gender standards start to change and shift, it will dissipate. i am a bi-guy with a trans partner, so i see it happening, but it will take a few generations to sink in... so maybe when i am in my 80s?

interesting topic! i wish we had some polled stats to look at to see how kink communities trend.
