Being totally incontinent, my backside has a mind of its own. I can mess sometimes 4 to 5 times a day, and I’m assuming at least twice in my sleep in a 24 hour period. It usually happens anywhere from 15 to 60 mins after I ingest any kind of food. So, to stay on topic: My FAVORITE position to poop is on the toilet, because if it does happen, it’s only because I’m in the bathroom in the middle of changing my diaper. Cleaning poop off the tile floor sucks!
