while you can talk a girl into feederism, you can force them in anyway or at anypoint to do so.
Like you mentioned with the dominant feeder, she should be able to force you do eat once you out on a date. The player has no power to do so in the current version.
Plus dominant feeder being able to hunt the player down to stop them from stay fit sounds like a real cool idea 💡, in a horror kind of way.
