You can always state you accept donation but in ten years I have been in the feederism community I got maybe ONE donation. Ever. And I do HQ content and tried to cam rOFL
So will you GET them? Probably not. But it never hurts to have that avenue .
Another thing is to grab rapport and allow yourself be known, i know some of the super famous in the community models like RosieMarie or them DO get donations. So you'd have to REALLY put yourself out there and get a fanbase.
I don't agree with the comment above. Gender has nothing to do with it, in fact one of the most successful feedee I know is a husband, wife team and the husband has a big thick belly and his wife and other skinny girls LOVE to feed him, love to watch him eat, etc . So there is a huge fanbase for males, in fact i have noticed there are more masculine folks than feminine in gaining.
But it is hard to get donations, thus why people have feeders
