eating ass sounds sexy if you're on the receiving end..
but I feel pity for the person who is doing the licking, not only does feces contain an "ass load" of bacteria (pardon the pun!) but its got to taste rotten as all else... and not in a cute "hehe your so rotten and filthy what a turn on" its literally gross...
I've eaten pussy but I've never eaten ass before... and I don't plan to. At least pussy tastes good
I'd probrably prefer anything over the taste of manure though
