I think the really cardinal rule about consent, the one which I consider to be entirely non-negotiable, is that it may always be withdrawn.
This is also true at a soup kitchen or potluck - people who come to your meal are not obligated to eat your food.
There may be social consequences - someone who shows up at your potluck and turns their nose up at the offerings may not be invited back, but they’re still under no actual obligation to eat your food.
