No, for two reasons:
1.) I'm not a neat freak about cleanliness, but I *am* too priggish to get anything up my ass. Believe me, I've tried, and even when it feels good there's always the nagging "This is so fucking gross--I'm going to need to take a shower and wash my hands 10 times" mantra going on in the back of my head.
2.) I won't do to a woman what I wouldn't agree to be done to myself. I wouldn't engage in anal with a woman for the reasons outlined above, so I wouldn't want to be shanghaied into anal either. Even in porn anal doesn't turn me on as much as straight sex, so why should I bother in real life?
Of course, never say never, as I like to say. As it looks now though, I'm not keen on the idea at all.
