Talk or no talk, stepbystep, all that happened here was that the movie was a cue or trigger, and your reacting to it created further urges. That is all.
Simply train yourself to not respond to urges (even if cued), and you will beat this addiction.
I understand the thought to somehow excuse or make room for these behaviors, and normalize them... I would say things like, "I'm a man..." Or, "I have special needs that PMO helps me with...", and so on. Or, "I need this..."
But there's a reason why you and I came to this forum, there was something that we needed to fix, to undo. And remember, too, that the porn industry is a multi-billion dollar enterprise. They may promote some of these "Porn's OK" type of shows....
Wishing you well.
