I've never really considered it, and I don't think the idea is very appealing to me.
(note: I'm not turned off by the idea, it just isn't a specific turn on for me)
If my SO wanted to try it, I wouldn't say no. But it has never been brought up...
Edit: Like Shanifaye said, I assumed by the wording of your question that you meant anal sex as man-to-woman. Whereas the other way around is also possible, and my thoughts lie a little bit more on the adventureous side there
