Time to take control of my life

My life has spiraled out of control, and nobody around me knows. This might be a bit of a long story

From the outside I have a great life. I'm 31 years old and have a good job, I own a nice house in a quiet neighborhood in the midwest USA, and I have 3 beautiful children and a wife who is much better than I deserve. So far so good right?

Now for the ugly part. I have been pmo'ing since I was around 12 years old, and started watching porn in my early teen years. I got caught a couple of times by my parents (the family had one computer) but I quickly learned how to cover my tracks, a skill which has carried over into married life. As I continued through my teenage years, my fantasies veered into increasingly bizarre and violent territory.

When I got to college my porn habit became a daily thing, and sometimes I would have an all weekend pmo marathon when I had the room to myself. It was also during this time that I started the dangerous habit of posting and responding to online sex ads and meeting random men and women. Eventually, I was letting them beat me, abuse me, and use me sexually in just about every way imaginable, trying to bring to life the brutal images that porn had burned into my brain as a teenager.

I always thought that getting married and having a family would replace those parts of my life, and I was wrong. In fact my wife know's nothing about any of this. I don't want my wife to have any part of these demented fantasies of mine. At some point, I devolved into meeting random strangers in public restrooms, and getting on cam sharing chat sites and masturbating for strangers on camera. Recently I had to take a road trip by myself, and spent hours trolling public restrooms and posting sex ads in various cities.

Ok I've never laid that all out before to anyone, and now I'm crying and feeling like a monster...

In the past few weeks, I've started trying to make some positive changes, including starting therapy for the first time in my life. Admittedly, I haven't gotten comfortable enough to start going through all this with my therapist, but we're working through the anxiety and depression that I've battled since I was a little kid. My parents didn't believe in mental healthcare, and if they read all of this, the part they'd probably be the most ashamed of is that I'm seeing a shrink.

Anyway, I had a realization tonight, that if this doesn't end it will utterly destroy my life. I know this is all more than just pmo, but that's where it all goes back to, and it needs to end right now. Tonight. This exact minute. Never again.

So here's my game plan:
1. No porn, masturbation, cam chatting, or anything related. If I wouldn't do it with my wife in the room it's a no go.
2. Delete everything related to this. Memberships on sites, burner email accounts, etc. I've started looking into software to filter internet in the house.
3. Keep track of my progress and give myself rewards at certain marks 30 days, 90 days, etc.
4. Focus on my physical and mental health. Stay in therapy and build up the courage to approach these topics. Improve diet and exercise habits, and sleep.
5. Use my time to work on developing skills and hobbies

I know this is long, and I apologize for that. I've never told anybody about this history and I went back and forth on it, but maybe I can serve as a warning to somebody else. I see so many on here that are teenagers just starting to get alarmed at what they're seeing going on in their lives. If that's you read above and see where it can lead, and ask yourself if that's who you want to be.

I need help becoming a new better person. At this point I don't think I can get much worse...
