After the results were published, the French declared that the British were wrong and decided to conduct their own study of the same subject. After three years of research and a cost in excess of $250,000 they concluded that the head of a man's penis is larger than the shaft is to provide the woman with more sexual pleasure.
When the results of the French study were released, Australia decided to conduct its own study. So, after nearly three weeks of intensive research and a cost of around $75, the Aussies study was complete. They came to the conclusion that the reason the head of a man's penis is larger than the shaft is to prevent his hand from flying off and hitting him in the forehead.
