Hello Reb Happy!
Just posted something on your other thread also. Sounds like you've found many different ways to get your lust fix. The first step is recognizing that you're addicted. The next thing is to recognize what you're addicted to. It's not porn, or this or that, it's lust. There's a section of your brain that demands stimulation via lust.
How to stop? To stop successfully, think of this addiction like addiction to alcohol. Cutting back doesn't work. Switching from vodka to American beer isn't enough. We all know that an alcoholic can't take even one small drink. Because as soon as he does, he's back to being a drunk faster than he can say "bartender!"
To break free, we need to cut off all our sources of lust. This is primarily via two avenues: what we see, and what thoughts and images we allow a seat in our minds. (Since you're married, there's that third avenue, but let's leave that for another time soon.)
So from right now and on, practice extreme shmiras eynayim in all settings. Commit to not looking at any women unless absolutely necessary. Including in the newspaper. No women. No part of them. Not even ugly ones. Don't even check out your own wife unless for immediate tachlis. Lust is lust.
When lustful thoughts come, start davening IMMEDIATELY, before the thought takes hold. Here's the tefilla I use when lustful thoughts come (including the thought that I want to DO something lustful):
"Ribbono Shel Olam, I am powerless over lust and my life has become unmanageable.
Only You can restore me to sanity.
I turn my life and my lust over to Your care and ask You to please heal me from this illness of lust. I don't want to lust, I only want You and a relationship with You and Your Torah, and appropriate attraction to my wife. Take my lust. Please, take my lust."
It works. It's called sobriety.
Hatzlocha!
