Honestly, I see the value of not having "counseling" about the *advertiser censored*/sex addiction right away. His brain is now wired to be turned on by the *advertiser censored* and I don't know that focusing on that will help at all. If you want to something to grow in your life, you focus on it and give it attention. If you want something to wither, you neglect it. So, I think spending a considerable amount of time AWAY from the computer and away from the unhealthy stimulation including conversations is needed before any progress can be made.
Yes, quiet time working on repetitive physical activities can be very beneficial in healing and allows the mind an opportunity for deep introspection (if he's capable of looking within, which I'm not sure about).
The *advertiser censored* obviously was pleasurable to him. He needs to find something else that gives him that same pleasure. This is the crux of the problem, imo. He doesn't KNOW the answer to this. He's been told all his life what to think and what to do (in public). He "honors his father" but honoring doesn't mean you follow a dictator! That's not honorable on either side! Josh has never been his own person, except in relishing in inappropriate sex. He needs to start over from scratch and figure out who *he* is besides Jim Bob's offspring. If the counseling is just to tell him what to do and think, that will not help any more than Jim Bob's dictates have helped. He needs to figure this out on his own, and any rehab should be providing the support and environment to do that.
He also needs to be taught that he is an individual who can create his own, fulfilling life and make his own contributions to the world...and that's true for EVERYONE, including his wife, sisters, and daughters (and gay people too...all the people he bashes have this same birthright). Once he gets this idea in his heart, progress can be made. With hope, this discovery about life will be more pleasurable and exciting than *advertiser censored*. This will take time - and it's something that should've been started when he was a child but instead he got his hand slapped for wandering off the blanket. But, it's never too late. If he doesn't do this, I have dim hope for recovery.
By "*advertiser censored*," I am referring to all his problems about sex. I know it's inaccurate to lump it all under "*advertiser censored*" but it's easier.
However, if he's a sociopath, which I have some suspicion he is, then this is all moot. I don't think there is a cure for that.
I have no idea if this rehab program will work or not, but I do see great value in physical work and saving "counseling" sessions until some addictive habits like using the computer for sexual stimulation are broken physically. After that happens, then I think the counselling can begin at a deeper level.
I don't see this a quick fix and hope he doesn't emerge in a few weeks claiming everything is fine.
Just my lonely opinion.
