Nudity is shameful , and viewing it an accursed sin . No exception is made for the private home or the marriage bed. A son-less woman who becomes widowed must have sex with each of her deceased husband's brothers, in turn, until she gives birth to a male heir. Sex between heterosexual singles is not condemned, so long as the woman is not a virgin, and her property value is not being diminished. Semen and menstrual blood are unclean , as are those who come into contact with them.
Sexual uncleanness lasts until sundown.
Menstrual uncleanness lasts for seven days. Childbirth renders a woman unclean. She remains unclean twice as long after having a female child , as she does after having a male child. Prostitution is natural, and necessary as a safeguard of the virginity of the unmarried and the property rights of men, as regards their women. A man visiting a prostitute is not sinning, but the prostitute is.
