My girl doesn't like going anywhere near my face, she prefers to curl up in my pocket and sit there with her head sticking out, and occasionally she'll yawn...
Munch does it a lot more, he flicks his tongue in my ears, up my nose, in my eyes, and is just a hazard to himself when he decides to wrap himself in my hair and THEN yawn... managed to get a bit of my hair stuck in his mouth so had to get that out xD I don't mind it, I think it's cute (not to mention I make a yawning noise when he does it) but my other half isn't so sure!!
