Most likely he will fall back into the same thing or worse. All the above does not put out the fire, it only adds fuel to it, and it is not fulfilling. Sexual immorality, committed by a married person, is a form of adultery. The sexual act is for procreation, and for the benefit and pleasure of the lawful spouses. It is to be shared between lawful spouses and not to satisfy the individual's lust, as in masturbation.
Masturbation is a perverted sexual act.
It is wrong and sinful, in or outside the marriage. It usually is accompanied with lustful thoughts and unclean fantasy. Masturbation will also stimulate the flesh to more sinful experimentation, as with vibrators, sex toys, pornography and such. Because it is sinful it does not satisfy and it becomes a habitual force in one's life. At morning light they practice it, because it is in the power of their hand.
