What's a better plan?

First and foremost: Do you intend to stay away from P for life? If so, what do you define P as? Videos, pictures, stories, fantasies, memories? If you being using M 3 times a week, will you be able to avoid those items you define as P, or will you get frustrated that you can't O and start slipping? Do you have a plan to prevent slipping?

Do you have any moral or religious reasons to avoid MO? Would you feel comfortable telling your partner or spouse that you M 3 times a week?

These aren't questions meant to absolutely discourage you; but I do think they are questions you'll want to answer if you want to return to M. Don't wait until the heat of the moment to invent a plan.

If you want my personal opinion - I do not believe M is inherently better than P. I am going to strive to avoid both for the remainder of my life.
