Body inflation

Don't have to it sticks out already

I used to, but I tried after reading this and I can’t anymore.... there is no difference/my belly is already extended, I can try to suck it in but that hurts.

I do this on webcam sometimes when RP-ing, I pull my belly in first and then push it out so it looks like I'm inflating

Yes, usually I can. The picture where I had two fish and 20 nuggets, I could still push my belly out a little bit. When I did, it felt like it was stretching slightly.

I can stick my belly out several inches from my “normal” appearance, especially lying down. See my profile page.

Yup! I can push my belly almost 1 cm.
Ive been able to di that since i was little.
Also since my appetite isnt that big whenever i do 2 litre water bloat my belly does push out by an inch

Yes, I can.
