Ear fetish?

I recently started talking to a boy and we were making out for the first time. He started kissing my neck and then went to my ears he would lick the outside of my ear and all around on the inside. He wouldn't kiss my ears, he would just lick them and kind of thrust his tongue in my ear? After awhile I kinda thought it was gross and I would grab his face to make him kiss my lips. But he would keep going back to my ears. Has anyone ever had someone do this? How do I tell him that I don't really like it? At first I enjoyed it but there was so much spit and all I could hear was his tongue swirling around. Ugh he is cute but ew. Help.
