im not sure id consider this humiliation! it's extremely dangerous! do you know that you can control an eating disorder but you're never actually cured of it?
and to fuck with someones head with it can be extremely damaging! even if she agreed to and enjoyed it, it's re-einforcment no matter how much control she may have over it ..its like giving an alcoholic a glass of champagne because its christmas.
i have an ED and there have been times ive been in control for fairly long periods too but had anyone ever done anything like that to me no matter how aware i was and reassured that it was play only i would have flipped right over the edge! sometimes just because someone gives consent to something it doesnt mean that makes it ''safe''
it's a mental health disorder ie: a serious illness...not just a body issue to be used for a game.
it's ok to say it's a matter of judgement but somethings cant be judged or simplified that easily.
im sorry i dont want to change or spoil your thread but that scares me its more than just edgeplay or a bit of kink and ok it's just my opinion but i really do think anything like that should be stayed well clear of.
