Anyone have any ideas on how to your non feedist partner or spouse in your kink.

It’s really hard sometimes to try and explain yourself to someone who doesn’t understand your kink. I would like her to switch to a more dominant role sometimes. And feed me or at least feed each other. I’ve told her this but I know she has no idea what she should do. She has always been very willing to indulge me but this is different. I told her I want to be the sub feedee more. I try so hard to describe what I want. She’s always let me feed her and gain in the process. But she looked at me like I have three eyes, when I said I want her to do to me what she’s aloud me to do to her. I get it this is not her kink. So I do understand. Any thoughts?
