The answer seems to be a resounding yes from Katie Couric on her podcast Next Question with Kate Couric. In the first part they look at how porn affects a relationship and the next part they look at how porn effects young people. Thought it was pretty good. It can be heard here or on your preferred podcast app.
Porn in general is changing or at least influencing us. I imagine society would be a much more harmonious place, without porn, alcohol and drug use.
