I'm in.
I've actually read the whole Your Brain on Porn site 1 week ago. So I haven't mastrubated or watched porn at all during that week.
I feel pretty good and it isn't that hard so far.
Things that helped me:
http://www1.k9webprotection.com/ I installed this, the K9 web protection, protecting me from porn websites. It works great.
Deleted all the porn I had.
Made a calendar where I will daily cross out a date when I made it without watching porn.
When I think about fucking my GF, I stop the thought and think about something else.
I meditate daily, but this time to learn to observe thoughts, so that I can more easily stop the visual erotic thoughts.
Stop myself from "fake jerking', don't touch your dick when it's hard. Eventhough you do it and intend to not cum, just don't do it.

When I was with my girlfriend today, I radiated hornyness all over. I noticed I became much more sexually agressive and dominant over her. Imposing my will upon her. This had a great effect on her and on me. This is totally new to me, never did anything like it before. So for those people that want to be more dominant on your girlfriend: stop mastrubating and stop watching fucking porn.
Please, everyone taking in this challenge, read the WHOLE website:

If you have the knowledge to actually understand why it's bad to watch too much porn and mastrubate, then you have much more drive and power over yourself to stop this addiction. Trust me on this, read the site.
