Welcome. Your addiction is shared by many of us, as is her solution. What is more interesting is how her insistence on chastity has changed you psychologically and emotionally, and how those changes (if any, but it's pretty unusual to be locked without such changes) have affected your marriage and your intimacy, and whether you have become more submissive to her. Hope you'll share.
Welcome and I am locked because of the same masturbation issue. I was destroying our sex life and ours is now back to the way it was when we just met. Hopefully both you and your wife are now getting what you need.
