Water is life, sex is life.

Life began on earth in water from earth and water.
No matter how much life evolved to become better,
It is still required by everyone from asexual bacterium to sexual fucker.
Single-celled beings fucked themselves for ages and left babies in water.
Some kind-hearted beings loved others to introduce the word 'father'.
But practice of leaving the kids after birth in water changed much later.
Then mother became in truest sense a caretaker,
Followed by father, after leaving the old ecosystem of water.
Nobody can deny the correlation of sex and water.
Semen has limbless seamen swimming through the dark gutter
Competing, searching, and digging a pot filled with treasure.
Meanwhile the father is empty and the mother is wetter.
