(Disclaimer: this message isn't meant for everybody, especially those for whom porn-blockers are working for them)
Porn-blockers = I'm too weak to dismiss urges, or to make a different decision. Of course I don't believe this about you, brother. But, porn-blockers say to ourselves that with the kind of easy access that we face, we're too weak to deal with it. In still other words, porn-blockers disempower us.
Whenever we refocus the blame on outward things, porn-blockers, accountability groups, past traumas, triggers (the girl jogging, the bill boards), porn itself- as for how 'enticing' it all is, we disempower ourselves in the process.
A mindset shift is needed. Place all blame or praise in yourself, that, whether you fail or succeed (and I speak of the lapses we may have, not as being 'failures' as such, but as learning tools), we're properly aligned with what's true. Then we can evaluate our weaknesses, what we're doing to sabotage ourselves, and/or our strengths, those things we're doing right, and we can tweak our approach and habits to align with our goals to be healthier porn-free individuals.
Hope this makes sense, and please ask if clarification is needed.
