Walking Along the Beach

Walking along the beach I see the waves rise up
and then pound the shore,
spewing their foam.upon the sand..
What can i do with it, what can I make of it ?
The swelling, rising wave is a an erect penis.
(With it the man penetrates the woman's vagina.
He pulls it out right before it shoots forth.)

The wave pounding the shore and
spewing forth its foam upon the sand
stands for the man's  penis squirting
 upon the belly of the woman
(as a way to avoid getting her pregnant).

Thus nature offers us a lesson to learn.
But how many men pull it out before it shoots its load ??
Not as many as there needs to be.

Males: the weak link in the chain of civilization.

PS: the part in parentheses is not part of the beach metaphor.
but I add it so that the thing can work.
