Not really: Just like in any big city, some streets are one-way and some streets are two-way. A vagina is created or evolved to be a two-way street (penis in and out; baby out). However, 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 brown stuff is billions of bacteria, sometimes viruses, occasionally worms.
