Stay Pure (Sermon by Stuart Jones, June 2014.)
From the description:
"Paul isn't saying to keep your marriage bed pure when you feel like it. He's urging couples to do whatever it takes to protect their relationship from outward and inward temptations always. Those temptations might include inappropriate relationships with the opposite sex, emotional unfaithfulness, pornography, adultery, or rejecting your spouse's physical and emotional needs."
Its actively enforced policy is not in its website's primary pages, but in its sermon archives.
