Several years ago Italy funded a study to determine why the head on a
man's penis is wider than the shaft. The study took two years and cost
over $180,000. The results of the study concluded that the reason
is to provide the man with more pleasure during sex.
When the results were published, France decided to conduct their own
study. They were convinced that the results of the Italian study were
incorrect. After three years of research and costs in excess of $250,000
they concluded that it is to provide women with more pleasure during sex.
When the results of the French study were released, the British decided
to conduct their own study as they really didn't trust the Italian or
French studies.
So after nearly three weeks of intensive research and at the cost of
around $75, the British study came to the conclusion that the
reason is to prevent your hand slipping off and hitting you in the face.
