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?

Yawning in general is still quite a debated topic in science. Its purpose is not fully known.
