For a good yawn I need to really open my mouth and push/strain my jaw muscles. If that doesnt happen, then the yawn feels incomplete to my body and it happens again and again till it works “right”

What is the reason/body function behind that?

      No idea. I can open my mouth larger than most prople. Maybe my muscles don’t like the max stretch though. I can feel a joint sort of pop in place as I start to max it out.
