Why Is pornography a bad thing?

I am single and i want to stay that way. i like to watch alot of those 1970 exploitation films. I never had a Girlfriend mainly because i put no effort into looking for one( they cost too much). I have watched these type of movies since i was 12 and i never had desire for a Girlfriend. I also really do not want to worry about having kids or dealing with divorce. I enjoy solitude and i hate being touched. I want to be able to go where i want when i want and not have to ask someone elses permission. In my case why would porn be a bad thing especially since i do not want a relationship.
