Rocco, lots of us find it too risky to pass gas unless we are on the toilet, though I think soiling the wall, etc. is a much less common problem. Are you using a bowel slower like Lomotil or Imodium? These could potentially make it harder for you to pass gas, and thus in some cases could lead to more bathroom visits. There are also ways to reduce gas a bit, including dietary changes and Beano.
