If you're constipated and happen to have a vagina, you can press the back wall of your vagina with your thumb and squeeze the poop out like squeezing a tube of toothpaste.
Going literally shitty on this one. This will probably also be a decent survey of lemmy's demographics; every man I've shared this with reacts in abject terror while all the women who didn't know you can do this look like a divine revelation had struck them. 🤣
