EXOD535 The obligation of the husband to provide physical pleasure for his wife through the act of sexual union is one part of the general obligations of every Jewish husband to his wife, to procreate and have children. Therefore, refusal to have sexual relations with his wife makes the man into a sinner, according to the Talmud, Yevamot 62b and it is grounds for divorce if either the man Maimonides, Hilchot Ishut 14:5 or the woman 14:8 refuses to have sex on a regular basis. This obligation exists even if the couple has already fulfilled the obligation to procreate, thus demonstrating that the sexual act, in and of itself, has positive value in Judaism.
