I don't get why people are offended that people are surprised that so many people don't know the basics of their own anatomy... It is really sad and surprising, especially as many of us on here have gone through pregnancy and childbirth (and catheters??!).
How is not sad/surprising that people are not taught these basics? It's like when I watched Food Revolution and so many kids didn't know where milk or cheese come from. It's very sad. But not an insult to those who don't know it. It's a failure on both formal education and informal education in the home.
