The Bible doesn't mention how often a married couple should have sex. Undoubtedly, it will be a function of proximity, the stage in life, and even logistics. In general, spouses should communicate with each other and reach an agreed-upon resolution. One possible compromise is if one spouse initiates and the other refuses, the spouse who refused is obliged to re-initiate within twenty-four hours. First Corinthians 7:4 explains that spouses have both the right to enjoy each other's bodies and the responsibility to respect each other's wishes. A healthy sex life discourages sin as the couple learns to be satisfied with each other and grows closer.
How often should married couples have sex?
God designed sex to be an important part of a marriage relationship. Not absolutely mandatory, as some couples will experience extended periods apart or physical problems that will make sex impossible. But important nonetheless. First Corinthians 7:5 exhorts us to not deprive each other. If a couple's schedule is such that they are just too tired or don't have time, the couple needs to address the schedule. It is not scriptural to let this issue slide. Another sadly common issue is painful intercourse. For the health of the marriage, if one or the other spouse finds intercourse physically painful, he or she should seek help from a doctor or counselor.
