Use oral lubricant right before you start. When I deal with dry mouth and want to give my man a BJ, this stuff is a lifesaver.

Also, bonus: deepthroating became sooooo much easier

Personally, I use Biotene Dry Mouth Moisturizing Spray***. I spritz like 5-6 times into my mouth, hold it in my mouth for a few seconds and then I’m ready to go. (Bonus tip: use chapstick/Vaseline, or coconut oil on your lips if dry mouth gets them too)

(***Please note: as far as I know biotene isn’t labeled for the purpose of oral sexual encounters, so it could be harsh to some peoples’ sensitive areas. Definitely do some research, especially if you’re worried or you or your partner are sensitive to any of its ingredients)
