And if a man lies with her to have intercourse, so that her impurity is upon him, he shall be unclean seven days; and every bed on which he lies shall be unclean.

Also you shall not approach a woman to uncover her nakedness during her menstrual uncleanness.

if he has not eaten on the mountains, nor lifted up his eyes to the idols of the house of Israel, nor defiled his neighbor's wife, nor approached a menstruating woman;

In you men uncover the nakedness of their fathers; in you they humble women during their menstrual impurity.
