Do you all subconsciously suck in your stomach?

I have gut issues which has been generalized to IBS and I’ve just noticed that I tend to suck in my gut at all times, even at home with no one around, and when I notice it and sort of release the tension it can be a bit painful and then my stomach is noticeably a bit bloated. I’m surprised it’s not painful at all times as it feels like I’m compressing everything.

Anyone else have this?
