An American university funded a study to see why the head of a man's p***s is larger than the shaft. After a year it concluded that the head is larger to give the man more pleasure during sex. After that study was published, an Italian school decided to do its own study. After three years of research the Italians concluded that the reason the head is larger than the shaft is to give the woman more pleasure during sex. Canadians, unsatisfied with these findings, conducted their own study. After two weeks they concluded that it is to keep a man's hand from flying off and hitting him in the forehead.
