It’s not your fault. Tell someone. You’ll survive.

NASA has a paper on how to not poop for days. It’s on the Internet. Before space toilets there was only a space bag with finger scissor/scoop holes. It didn’t work, poop got everywhere. The paper goes into detail about fecal matter being everywhere after early multi-day missions.

So they figured it out. Their system works – I’ve also had my own reasons.
