Many a wife can tell you that getting married did not help their husbands. It just dragged them (and perhaps eventually children) into the mess, and then a lot more people are suffering.
It strikes me as not in keeping with the dignity of the human person to think one can swap out porn/masturbation and swap in sex. It could be that meeting someone special could be a motivator, but the skills necessary to overcome it can be learned prior to marriage and will help you be a better spouse: self-denial, sacrifice, the ability to turn aside temporal pleasures for the greater good. Masturbation affects your ability to truly unite to your spouse because of the way you condition your sexual response. A wife cannot read your mind, nor is she a man. Under normal circumstances, sex is awkward, especially at first, and it’s a skill people learn together. A wife has her own needs and limitations because she’s human, too. And somehow you have to be able to communicate all this.
IMO, perhaps the greatest allure pornography and masturbation have is that they are easy. No effort, vulnerability, communication required. Just instant gratification. These are precisely what it takes to be a good spouse. It would be wrong to go into marriage expecting your spouse to fix you.
