To be fair, bladder inflation is already a thing IRL, people just have to be picky about what goes in there and how clean everything is, since UTIs are a pain in the dick (hehe). Also I understand it makes people get difficulties peeing, like it ruins their bladder muscles so they have to use a catheter permanently. Still, some people (not me) would probably be interested in having a mechanic where drinking too much water would fill your character's bladder and THAT would be another method for belly inflation, and another stat to stretch out. That might be a bit too much of a niche appeal, though.

Womb inflation, yeah that's a no-no IRL. If you wanted to bypass real-life shenanigans with that, then you could have it be an unlock through Yumi, like if we got her interest in inflation high enough, she would be convinced to come up with a uterus implant that can be used as a sort of 'handwave' for the game to dodge any questions about health or safety. Maybe the uterus implant would work as a """permanent""" way to stay big, like it stays at whatever size and doesn't inflate or deflate unless you do it yourself.
