Many couples experience the benefits of role swapping within marriage.
Gender and sex roles are not fixed in stone. BUT - this type of gender experiment can go wrong unless both parties understand that they are in fact swapping roles. Contrary to popular belief this type of behaviour is more successful when accompanied by 'feminization' of the husband. No army would dream of training a soldier without putting him into a uniform that identified the wearer as a soldier. The soldier knows that by wearing his new clothing he is accepting both the role of soldier and at the same time he surrenders his freedom to another persons authority.
