A good friend of mine married a guy who was addicted to porn. The night before the wedding, he was downloading intenet porn. We all tried to tell her this was not good, but she married him anyway, because it wasn't an addiction, just a fun little pasttime. Fast forward two years later and she's upset that he depleted her checking account to pay for his "Barely Legal" porn.
In many ways I lead a "sheltered" life (ie I'm more or less a hermit) but I have known at least three men who've been porn "users" and they are all screwed up to the maximum, their wives are miserable, one child saw some porn and acted out with another kid what he saw, one of the men had a fiancee leave, then a wife leave, and the amount of deception and dishonesty that seeps out into all relationships is a lot.
Like many mental addictions, they just can't stay away. They always want more. One of them did the same thing - ordered some stuff that automatically got taken out of the bank account.
Porn ruins people and families.
