Is it permissible for a man to marry a second and third wife only for the sake of fulfilling his sexual desires?

Answer

It is permissible for a man to marry another wife even if it is only for the sake of his sexual desires just as it is permissible to get married to one woman for the sake of sexual desire. All men marry primarily for this reason. The other aspects, e.g. procreation, caring for the women, etc., are by-products. Despite their fundamental importance, it is furthest from the minds of men when they marry. Only those with exceptionally high Taqwa have the other factors of altruism in mind.
