I'm a Sex Ed teacher and go over the parts of the female anatomy, breasts, buttocks, and vagina. We discuss the parts and when you get to breasts in order to show and explain breastfeed I squirt breast milk into a glass. I continue on with the explanation and get to the urethra. I show the opening and discuss it, now, vaginas pee, so I fill the glass that had milk in it with pee and ... delicious! I dismiss the class.
