It seems that many users here agree that 90 days in a row of no PMO cures issues like PIED. I have some questions.. Why 90 days? Why not 45 or 60 or 120? Also, why does it have to be a consecutive streak? It seems hard for me to fathom how all your progress is essentially supposedly erased if you are on a 10 day streak and then relapse. If someone does 30 days no PMO, then relapses, then does 20 days, then relapses, and then does 40 days and relapses, he still did 90 days of no PMO, so why is he supposedly not cured just because of a few days in between? Please explain me if I am misunderstanding something, I am genuinly trying to understand, sorry if I sound ignorant.
