Captain: Seems to me that an OCD condition can complicate, or help, the process of rebooting. Are you getting help for the OCD? I would start with understanding and working on the OCD, then move into rebooting.
This said, I think it fair to say a LOT of folks on this site go YEARS attempting nofap. They try and fail, try and fail, over and over and over. I know, I'm one who couldn't make it a week without PMO. Then something shifted. I found a book and then this site and then the strength inside me to make it a week, then two, then almost three, then BAM! relapse. I thought I could edge by just looking at porn... doesn't work! So, what did I do? Pick myself up and try again, only this time 1) no edging, 2) watch for triggers and work around them, 3) discover a new mindset, one that doesn't involve thinking about PMO, 4) filling my time with productive activities, and 5) appreciating every day I not act out.
The results of all these actions and decisions is that at 2:30 pm pacific daylight savings time, I will have 49 days of no PMO! For the first time in my life I feel unashamed, free to choose, and clean. I know I am a long way from full recovery, but with only 49 days under my belt in reboot, I know there is a life that doesn't need PMO, that is filled with confidence and personal acceptance. And the longer I go, the more these positive feelings grow and replace the dark spaces of acting out.
What do you do when you relapse? You pause, hug yourself, forgive yourself, love yourself, then consider what happened and why, then reboot again, and again, and again. Reflection on what led you to act out will help you try different things during the next reboot.
Keep reading the posts at this site and respond to some as you need. A daily habit of reading and posting can keep the you focused on the goal.
