In marriage, sex is not some extra bonus on the side. It is part of the bond. It is one of the deepest ways a husband and wife stay connected, feel chosen, and protect closeness between them.
That is why it should never be treated like a weapon.
Not to punish, not to control, not to send a message, not to make the other person suffer until they finally learn. Because once intimacy becomes bargaining, the marriage starts changing.
Sex in marriage is sacred because it carries emotional weight. It reassures, it softens hearts, it restores connection after stress, distance, and daily pressure. So when it is constantly withheld without care, the damage is not only in the bedroom, it starts affecting the whole relationship.
