Nature has carefully taken care of its needs. In human beings raising a child is one of the most resource consuming jobs without much significant return. It makes no practical sense as why would we opt for such inefficient activity. But for the survival of any species, reproduction is the bottom-line. And God is not a fool. He knows what it takes to make it work. So he made sex. Moreover to make if more fun, He thought “lets take away their judgement ability when it comes to sex”. How else would you explain a species with highest brain is to body mass ratio, who are otherwise able to find the nuclear reaction going on in the Sun to the cause of global economic depression, to cheat on their spouse for few minutes of pleasure?
High school Biology class in progress. Todays topic- Life Process II: Reproduction.
Teacher asks a question to all students- What is sex?
Everybody in the class starts giggling.
Teacher asks again. This time pointing out a boy- You, stand up and tell me, what is sex?
The boy stands up, still trying hard to hold his smile and says- ummm… aaaa… sirrrr…
Teacher gets impatient and shouts- Stop stammering and say it loud. I can’t hear you.
Boy freezes in fear and starts speaking in a robotic monotonous voice- It is the penetration of penis into the vagina.
Pin-drop silence in the class.
Teacher looks away from him and says casually- Sex is the property by which organisms are classified as males and females. Anyway sit down.
