I can say from experience that you tongue can get tired - really tired from performing oral sex. I've had mine go from tired to aching, to the point where I really couldn't continue. (guess I need more exercise). Often my tongue is somewhat aching the next day. It may be that he just can't keep doing it for that long.
In the same way that men often don't under stand how difficult it can be to give head, some women don't understand how difficult it can be to go down on a woman.
I very much enjoy giving my wife oral, but sometimes after a while the muscles just aren't up to it anymore.
