Hey, as long as it helps prevent predators from "playing with your hair" when you're completely inside their gut, that's welcomed progress!
Only thing I can still see breaking is interacting with the belly and/or predators like slimegirls who have semi-transparent skin. (By "interacting with the belly" i mean as in feeling the prey's form through their skin or in cases when the skin is stretched taut like a bodysuit on the prey... but i doubt that can be put as a rule sadly. 🤷♂️)
