I have rimmed my husband before. And he really seems to like it. I've asked him if he'd like to experiment with fingers but he wasn't too keen on that. What really drives him nuts though, is not so much for his ass to be licked but that little spot between his "package" and his asshole. I forget what it's called, but it'll swell up abit. I generally play with that quite a bit whenever I give him head.
