My sister and I were nine and ten. We lived with our mom in a two room apartment. One night a man came to visit. She never let men around us. He was there for one thing and he got his one thing and left. My mother felt obligated to tell us about the facts of life. One fact she mentioned was that men wanted to have a woman, sometimes real bad, but to be fair sometimes a woman wanted to have a man, real bad. And that included her. She apologized for having him come over, it wouldn't happen again.
