I can honestly say I've NEVER been in a church service that directly dealt with pornography addiction or sexual addiction. The nearest reference to it are the slides before each service reading, "Struggling with addiction? Celebrate meets Wednesday nights." It's like they're telling you up front... "If you're struggling, we have a place for you, but this aint it." Am I glad there's a place? Sure.
I'm not trying to say all churches are like this. It's just been my experience that it seems like there's a mindset of, "There's a place to talk about addictions, but church isn't it."
How about you? Has your church talked about porn addiction?
