This was brought up in another post
Are All Men Prone to Cheating at Some Point. Rather than hijack that thread to discuss the topic, I decided it would be better to start a separate thread.
I see no logical way to associate porn with cheating, unless an agreement has been made between partners specifically regarding porn. I recognize the fact that porn has many negative aspects, but that does not make it cheating. I have always wondered what logic people apply when making the link between porn and cheating, so would love to hear thoughts from those who feel that way.
