LEV202 Women who rub one against the other--this is forbidden. It is among the acts of Egypt against which we were warned, for it says (Leviticus 18:3): “You shall not copy the practices of the land of Egypt.” The sages said (Sifra, Aharei Mot, 9:8): “What is it that they would do? A man would marry a man, a woman would marry a woman, or a woman would marry two men.” Even though this practice is prohibited, one does not receive lashes, for there is no specific biblical prohibition and it is not called “intercourse” at all. Therefore, they are not prohibited [subsequently from marrying] into the priesthood on account of licentiousness, and a woman is not prohibited to her husband on account of this... but it is appropriate to give them lashes [on rabbinic authority] for rebelliousness, since they have done a prohibited thing. Maimonides (Rambam), Mishneh Torah, Laws of Forbidden Intercourse 21:8
