What's next? Can you PMO?? Are you serious. What do you think this is, leveling up from a game or something. If your intentions are to PMO then what's the point of rebooting?? You don't go through phases to relapse again. There's people on this website with real problems, real issues and real addictions to porn. There's people on here who feel terrible about themselves after they relapse. So what's really your motives...quitting porn and masturbation is a lifestyle. Not some phase or 90 day challenge. Reevaluate your motives
Firstly well done on reaching your first goal! The literature suggests that it's beneficial to give up for 90 days so why not carry your streak onto 45 days (and then further but don't worry about that right now) Good luck.
