Basically, I think masturbation is completely normal and useful the sexual development of adolescents. Even in a relationship or marriage it should be mostly unproblematic, as long as the sexuality of the partnership is more important and is not affected.
Nevertheless, after twelve years of marriage, I gave it up, first as an experiment and permanently for the last 17 years. The basis is a kind of vow, not in the religious sense, but just as binding.
And why? The kinky part of my personality developed while my wife had no corresponding fantasies. After a while I recognized that the combination of kinky fantasies and masturbation might get more important compared to than intimate moments with my wife. I felt something had to change, we talked a lot and came to a solution: I gave up masturbation - for the first years without a CB - while my wife tried to understand and accept what I was missing. I have the impression that my wife is as happy with the result as I am. It's not perfect, sometimes the chastity belt is really a frustrating hindrance, but it's the best compromise we could find.
