Ever since the Neanderthals figured how to chisel shit onto walls, the world would never be the same ever again. For better or worse, porn in the prehistoric era was abstract at best as the troglodytes at the time were still figuring out how to have sex in the first place. Oral and anal sex came first. Those that understood vaginal penetration produced offspring and passed on their genes to the next generation. The rest were left choking on cum and dying humiliating deaths. Bodies were found with gaping anuses and atrocities like feces slathered penises only exacerbated the need for porn to guide how-to have sex. Only in the 21st century did oral and anal sex embraced once again.
So here is my tribute to pr0n where I detail the important "eras" of porn. (Like any adolescent, the internet was my gateway...)
The Artistic Age
Shortly after 500 BC, white people from Europe realized they could get away with porn as long as it was art at the same time. Porn at this time was tasteful and the church commissioned many artists so they could put porn on cathedral walls.
The Camera Era
Photography revolutionized porn. Now smut could be sent around and huge profits were being made. During this time, (i.e. around the late 1950s I presume) porn was battling against the petty morals of the religious right. At the time, photos were black and white and most of the time, they had articles of clothing on the girls while they posed in a suggestive manner. This was lame.
The video era
Finally hardcore porno was introduced. Stars were uncensored for the first time and no clothes was fine.
The Post-Martin Luther King Era
Black people discovered that they were beautiful too and people rediscover the sexiness of the Neanderthal descendants. Also, Dr. Watson retracts his statements that black people are inferior in intelligence.
The Ethnic Era
Asians discover plastic surgery. Girls are gaining confidence because being sexually repressed is unappealing and fucking a lot of guys is the new "in" thing. No, I'm not jealous.
The Japanese Intermittency
Japanese people once again fuck with our heads. Fucking Japanese people. What the fuck. I'm jacking off to Saturday Morning Cartoons and Pokemon.
The Liberal Era
Gay marriage debates. Lesbian sex. Porn is at its pinnacle evolutionary state. Finally girls are getting along with each other (and in some cases men). There is nothing more perfect than two girls going at it until our preconceptions of the human capacity to do utter and irredeemable evil is once again...
The Internet Era
NOTHING will save you from GOATSE. YOU cannot unsee this shit. What the fuck is wrong with you people?! Fuck you!
In other words, look up internet
rule #34.
Yes, my friend, this is the sound of your childhood dying.
