The gag reflex is triggered by the first powerful spurt hitting the back of your throat. While working on him, keep a thumb light against the bottom and base of his penis. You can feel the ejaculate pass through the urethra. As soon as you feel it, press the back of your tongue up against your hard palate. An alternative is to raise the tongue and take that shot under your tongue. I prefer the former.
This does nothing to make it taste or feel better but does protect the gag reflex.
