The real reason comes out. Lady, I am honestly really sorry about your friend. Cheating is a really horrible thing for many reasons. You are taking a person who occasionally watches pornagraphic movies (I haven't seen one in years) and extrapolating that to people who have contact with other women. Not the same thing.
It's not exactly the same but just as bad.
Real men work out problems with their wives. Abusive haters of women turn to porn.
And most of it is child porn because if anyone believe they do a real age check I've got swampland in China for you.
