Hi. There's actually nothing wrong with watching porn while you're married under the law of God. Married couples have way more benefits than single people under the law of God. As long as you're watching porn with your husband you should not feel guilty from this.
It's ok to enjoy porn. My husband and I watch porn almost every day and we don't consider ourselves addict. We enjoy it with each other. Now if you are acting out in ways that are putting you or others in danger because of porn then you need to seek professional help. Porn is NOT BAD as long as you are not acting out. Porn can actually enhance your relationship with your significant other as long as you both enjoy it.
