Anal in general is only okay to me--I'll do it if a woman really wants it, but I won't press for it otherwise.
That said, I had one lover who was crazy about it, and who was similarly crazy about eating cum. She would scoop it out of her own pussy or ass to eat (or out of my wife's pussy, or lick it off her breasts). She loved, loved, loved ATM, because it combined two of her favorite things. She liked me to start off in her pussy, then, when I was nicely lubed from that, move to her ass, and when I was getting close, move to her mouth so she could take dessert directly from the source. Never any health issues or cleanliness problems, and it was a huge turn-on for me that she loved it so much.
