Why do people watch porn?

Your assumption that sex is somehow degrading to the human body is just plain wrong. Sex is the greatest thing in the world, and there's nothing wrong with sharing. Luckily enough if you don't like porn then you don't have to watch it. Heck, there are many countries where it's banned. Unfortunately in most of those countries you'd probably be stoned for speaking your mind. I mean those sorts of countries look down on women with an opinion. Luckily for you you live in a Nation that believes in freedom. Be thankful for that.
