Cattastrophe:
Where do people find feeders, because I don't know where to look. Both online and irl recourse are welcome. Is there a place to find gay feeders?
When I want to find a feeder, I look in the mirror.
But in all seriousness, there isn't an easy, centralized place to find female feeders - lesbian or otherwise. Most places are oddly hostile towards us. And as far as I know, there isn't a lesbian version of Grommr.
Your best bet is to look where feedists in general hang out. FF, Feabie, WooPlus, Fetlife come to mind. I know there is a decent feedist community on Tumblr. But Tumblr isn't a dating site.
You may need to be the first to approach. Alternatively, you can take a stab at personal ads. Either way, you'll need to be patient. Lesbian feeders are out there looking for a lesbian feedee.
I wish you well.
