Depends on activity: Just like in any big city, some streets are one-way and some streets are two-way. The gastrointestinal tract is designed to be one-way, with an opening on each end. Food goes in the mouth, and the brown stuff goes out the butt (the exception is when one vomits). Interacting with the outer anus is "harmless", but recreational insertion of objects into the anus is not considered a good thing to do.
