I think you are the one who is ignorant. You just gave the explanation yourself. You should know it takes time to go back, it is not instant. If you paid attention you would have known that.Sorry. You're wrong. When a vagina takes something 13 inches long, and 9 inches in diameter every day. Sometimes multiple times per day for years, she stays sized for something that big. And saying otherwise is just ignorant.
Why does the name George Carlin pops up, I don't know.
However, if a vagine stays open, then the woman would be.more receptacle for deceases, because her internals would be exposed. Therefore the amazing machine called body developed in a way to protect the woman.
