Why do men still sleep with their wives when they don't love them?

Men may sleep with their wives despite lacking love for various reasons, including a desire for physical intimacy, emotional connection, or companionship. Habit and comfort can play significant roles, as long-term relationships often maintain a level of physical affection even in the absence of romantic feelings. Additionally, societal or cultural expectations may pressure individuals to uphold certain marital norms, including sexual relations. Lastly, some may seek to fulfill emotional needs or avoid conflict within the relationship.
