Fast forward, I just had my 33rd birthday. I haven't looked at pornography in over 5 years. But I'm still struggling with pulling out my hair. And that's how I know how much of a stronghold this has on my life. I do it mainly when I'm self-soothing or just under a lot of stress. I know my triggers and I still can't defeat this thing. I have tried N-acetylcysteine, shaving my hair short, prayer. My wife will even swat my hand down (bless her heart) if she sees me reaching for a hair. But then I end up getting mad at her for not letting me have my fix.
My theory is that I don't truly value and love myself and that's why I'm willing to inflict damage upon myself. Sometimes I even use pulling to "punish" myself for not understanding technical things. It's self-mutilating and there is a lot of shame and guilt associated with it.
I'm still hopeful that one day I can overcome this habit (disorder?). I sure as hell don't want to have kids and have them grow up watching daddy pull hairs.
