Evolution has led us to our physical bodies as they are now, possibly with a little bit more skin than some of us may have. Regardless, there's the function of procreaton. You see, in our to sustain the race, one has to perpetuate the species. In order to do this, the act of reproduction has been made enjoyable mentally. It is percieved as a pleasurable experiance. So when a man loves a woman, physically, they are both just acting out generations of evolution. It's made pleasurable so the species doesn't die out. Now comes the problem, society. Society doesn't like men and women doing as they please, so there are a bunch of rules. These rules were specifically designed to counter our natural instincts. In order to survive within society, man created porn.
Pornography, in its purest form, allows a man to not hurt anyone while keeping himself healthy. No women are hurt, as long as their permission was given to use those photos/videos, and no men are hurt, being thrown in prison for rape. oh, and the rape victims as well. People say that porn objectifies women. I say men objectify women. Without porn, men will only devalue women more. In the dark ages of Europe, there was no porn, and women had no rights. In the twentieth century in the USA there was porn, and women got voting rights. Corrilation? I think not, ...but maybe there's something to it. The more full of "fury" a man is, the more he's gonna see what isn't there. Even if women don't show the least bit of skin, if a man is at his breaking point, he'll see curves on a lamppost. If you want more violent crime, rapes, or misguided teenage fads (goths, punks, sciencetologists), then fine, ban the porn. But if you want men to remain calm in society and look at women for the people they are, you need them relieving themselves to porn. That way, they aren't thinking of reproduction while the women are talking about equal rights. In American society today people all say it's bad, but they then go home and do it themselves. We're expected to look down on it but know better, and do it in secrecy. The problem there is with the youth. They are confused and impressionable, so they hear the adults saying don't do something they feel like doing with all their might. So they look at the adults, who have sex with their partners, and do the same to empty their chambers. That's why you have teenage pregnancy. If you were overloading these boys with porn and strippers, they wouldn't have time to knock up their girlfriends, they'd be too exhausted. So if you want a better society with less teenage sex, less focus on sex in general, then just let the kids do what comes naturally to them. Don't necessarily encourage it, but don't discourage it either, let them find their own moral compass. In the end, if you're side is right, people will arrive at the same conclusion on their own.
