They are mutually therapeutic. It is the nature of marriage that a couple will have differences when they live so intimately day in and day out. Every marriage has stress periods, but when we talk about our experiences and ideas together, we come back to appreciate the uniqueness of the person we chose to be our companion. They date frequently to renew their relationship. They want to get away from phones, children, and distractions.

Sexual relations is a form of therapy for married couples. It is not to be used or abused by offering a mere pittance, nor is it to be on-demand. Sex is not to punish or to use as a weapon to hurt the other. Non-sexual affection is the key to enjoying your sexual relationship. Because sex is somewhat of a barometer of the quality of the marriage, what occurs in the other areas of marriages affects our desire for intimacy.
