Thermonuclear reactions need enormous pressure.
You cant have so much pressure on the surface of the star.

scientists once discovered that if those reactions would happen on the surface the star would burn away like a firecracker
in fact thermonuclear reactions happen deep within the star and surprisingly seldom in relation to the hughe mass of stars.
otherwise it can't be explained why stars exists for billions of years, since they don't have an infinite ammount of mass to burn.

Hydrogen fusion requires at least 17,999,540.33 degrees Fahrenheit. This temperature doesn't exist on the surface of any stars. It's only in their cores.
