how to work with a big dick?

My ex (first) was like 5 inches and not very thick. It was extremely easy doing anything to him. My new panther is 9 1/2 inches and nearly twice as thick as my ex. He came over and he ate my pussy like a god! But when I was blowing him I was having such a hard time doing it. Not even halfway down his cock was hitting the back of my mouth and he was too thick to get down my throat! It also took so much saliva to try and get him wet enough to stroke. We haven't had sex yet but plan to and Idk how to work with such A big dick! Tips???
