There's an interesting parallel in marriage. God designed women to need leadership from their husbands in order to feel loved. Not only did God give the husband the position of authority and leadership in the home, but He did so because it is best for both men and women.
Men have a need to lead. They're designed for it. They don't feel loved if their wives don't follow their lead. At the same time, God made women to need to be led. They don't feel loved if they are in control. They feel abandoned and lonely when they aren't following their husband's lead. They need the husband to be the head, to lead them and protect them - physically and emotionally.
