Does sucking dick make your jaw more refined?

Just curious if anyone else has noticed a more chiseled jaw from continued cocksucking

I don't know about refined, but definitely more conditioned, so perhaps by default it becomes more muscular. I do know that years ago I stopped getting jaw tiredness or soreness from a long suck session. So regular cocksucking definitely improved the muscles and tendons in my mouth too facilitate extended sessions or larger cocks.
