A young boy caught sight of his mother changing one day and asked her what she had between her legs.
"That's something you're never going to talk about again. And you shouldn't touch it because it has teeth," she replied.
Many years went by, and the boy never touched any girl in between her legs because he was very scared.
One day, however, he met the love of his life, and they got married.
On their wedding night, his wife asked him to touch her there.
"No," he said. "It's got teeth."
"Silly goose!" she said. She spread her legs wide for him to see. "See? No teeth!"
"Well, I'm not surprised," he replied."Not with gums like that."
