Is Pornography Always Exploitation?

There are those who say that pornography exploits the ones who appear in the videos and photographs. I know that this is possible in some cases, but I do not think that it is true in all cases. There are people who participate in these activities, because they enjoy doing it. I do not condone anything that exploits anyone, but I see nothing wrong with pornography when all involved in it get involved in it by their own volition. I have heard it said that it is legalized prostitution. I do not see anything wrong with that as long as it is done willingly by someone who is of age. I have heard it said that pornography exploits women. Not all pornography involves women. In the case of pornography that does involve women I can see nothing wrong with it as long as the women involved in it do so willingly. I am firmly against exploitation of any kind. To me it seems more harmful to see the presentation of violence than it is to see the presentation of consensual sex between adults. There is also written pornography which exploits no one. Then there are the free websites where people post videos and photographs of themselves performing sexual acts. How is this exploiting anyone? No one is being forced in any way to perform or to watch. Some people are excited sexually by the thought of someone watching them. As in many things, pornography cannot be painted with a broad brush.
