hey ! ... I'm not kidding ! ....
I remember reading somewhere about that ! ....
the design evolved in reaction to human behaviour ! ...
other primates, say gorillas, have proportionately smaller dicks
cos their social structures are centered around an alpha male and
his harem, i.e. he can be reasonably sure that his kuku is the only
one that enters his harem's ... holes ....
but human beings are another matter ... you can't be sure that
you're the only one dipping the wick .... so, to increase the
chance of actually successfully breeding with your chosen mate, big
kukus and a large head with a prominent ridge is an advantage ....
monogamy may be central to the social structure of much of our
species, but nature certainly didn't evolved that way ...
