XX Male Anatomy

Three British educational institutions were commissioned by the
government to discover why the human penis is the shaped the way it
is.

Oxford University allocated a budget of ₤500,000 for research. After 2
years they concluded that the reason the head of the penis is wider
than the shaft is that it fits better, when in situ, so to speak. This
would prevent leakage of semen and increase the probability of
successful fertilisation.

Cambridge University spent ₤750,000 on a research programme that
lasted 3 years. The results showed that the penis widened near the tip
because it maximised the number of nerve endings stimulated during
sex. This would lead to increased sensitivity and a better chance of
impregnation.

Finally, the Open University spent ₤2.50 on a copy of Playboy and 10
minutes in the staff toilet, only to discover that the penis widens at
the tip in order to prevent your hand from slipping off the end.
