Jane explained to him what sex was.
Tarzan said, "Oh, Tarzan use hole in trunk of tree."
Horrified, she said, "Tarzan you have it all wrong, but I will show you how to do it properly."
She took off her clothes and lay down on the ground. "Here," she said. "You must put it in here."
Tarzan removed his loincloth, stepped closer, and then gave her an almighty kick right in the crotch.
Jane rolled around in agony for what seemed like an eternity. Eventually she managed to gasp for air and screamed, "What did you do that for?"
