Speeches / SPEECH on Having children in an appropriate age [2]

I wasn't sure where this should be placed, as I'm new, but I guess this could count as a small speech. It's a message I sent to my friend.

We began getting onto the topic of having children when we get to an appropriate age, and I got to a mindset where I couldn't stop thinking, and who better to tell my thoughts to than my good friend, Anna.

It's a bit jumbled, as it was sent via text message, but I'd really like to turn the basic thought into an essay. Any ideas/tips on how I might spread the small thought into an essay I could give to my writing teacher? The text message; *warning, mild sexual themes/topics*

As odd as it sounds, I like any physical-sexual relationship between genders. Guyxguy guyxgirl girlxgirl. I love it all. Its so passionate and the fact that they can share one of the greatest pleasures with each other is so passionate and strong... but then I over think things and realize that sex is only so amazing because nature made us one of three species that has sex for pleasure. It shows that our free will gives us the option to not breed, so nature gave us incentive, and boy do we use it. That's why I'm not having kids. Nature made a crucial mistake by giving us free will, because with it we have the power to go against the natural order of things and completely destroy the earth for our own selfish, ignorant needs. Sickens me, really. Which is why I'm not having kids. My gift to nature, not reproducing. It wont stop humanity but it'll at least respect the fact that humans should never have bred since day one. It's brought about the definite doom to our world, and not having children and continuing to keep the species going is at least putting the effort (or lack, thereof) to not show that I support what our race is doing. And sometimes I wonder. If nature makes everything according to a plan, maybe it's plan WAS to destroy our world, maybe the world has come to an end, and we are the reapers.
