Q: Pooing during anal?
A: I do love the brevity of this question. I imagine the question asker is concerned about accidentally defecating during anal sex. This is a common fear for people just starting to have anal sex. Thankfully, when you penetrate the anus, you're really just penetrating the rectum, which typically doesn't have any fecal matter in it. Feces (if any is present) is much further back in the colon. There is a natural bend to the rectum, so that a penis, finger or anything else penetrating the anus is very unlikely to come into contact with the colon.
That being said, it's always a good idea to go to the bathroom before having anal sex. Fecal matter can enter the rectum if you *really* have to go; and having to poop when you're having anal sex is bound to be less than enjoyable. But, if you've recently gone to the bathroom, there's nothing to worry about.
