Christians: Should married couples indulge in ponographic films?

My friend and i were having a conversation regarding this and we had some disagreements. I do not believe that Christians (married) should be indulging in watching ographic films to "spice" up their lives. Moreover is a very serious act and there are many unseen consequences that are attached to it.She disagreed and said it it was quite ok and nothing is wrong with it. I know that people who are normally on these films are not married so they would actually be fornicating....should a Christian get kicks out of watching this? There are many other reasons but i really do not want to get in them. My church does not really teach on these issues so i am left to form my own opinion. Consequently i am throwing out the question to get q wider view on the matter. thanks
