Hey guys
I’ve been seeing this guy in the past month who’s really nice and we’ve been experimenting in bed a bit.
I’d never thought of bringing feederism up before because my attraction is mostly to seeing someone outgrow their clothes / eat until they’re helplessly full / being generally greedy in a way that has weight-related consequences, but unintentionally. Being the direct cause of that is something that I find immoral, since none of my partners were ever into that kind of thing.
Anyway, I think this guy has some sub/shame-related kinks that he hasn’t fully shared with me yet. He likes food and he likes cooking and he often eats too much. I find myself thinking of trying to somehow play into my fantasies in real life, if he’s into it.
What are some practical ways to start? How would you bring this up?

If applying a term, I highly recommend "feedism" rather than "feederism". It sounds sweeter and takes the emphasis off of the feeder to be inclusive on both sides.

It might be worth casually starting up a kink-related conversation. You could start simply with that you like seeing him enjoy his food and it turns you on a bit, or something similar to get a sense of how he might react. If he volunteers that he has any sub leanings, perhaps you could ask to feed him. Starting soft and feeling it out could be a good play.
