answer:Most women don’t drink their own milk, and I’ve only heard of a handful of people who have made their own **** or bread from yeast cultured from their own body – and those were unusual enough to warrant media coverage. I’m told most men have tasted their own semen, but I doubt many of them are gulping it down like slimy Gatorade. If humans laid eggs, I doubt they’d eat them. Besides, if you make a mistake with using a fertilized bird’s egg, you just end up with a few spots of blood in your egg. If you make a mistake with fertilization of your own egg, you turn into Lamia. (And women do lay eggs. The eggs are just too small to be seen with the naked eye. I have a pagan friend with extremely heavy flows who uses a menstual cup and uses her excreta to fertilize her plants. She says it puts her in contact with the goddess.)
