Judaism and Protestantism share Catholicism's sexual ethic. All are derived from the Ten Commandments and Hebrew scriptures. They include a prohibition on extra-marital sex and calls for modesty. He whose wisdom transcends the fashions of the day and idols of the age. By the way, feminists have it backward.
Biblical morality seeks to restrain the sexual urges of men far more than women.
Even after decades of cultural brainwashing, women are still more modest, monogamous and selfless than men. In Jewish law, women are exempted from many of the positive commandments that apply to men, on the theory that they begin on a higher spiritual plane, while men, being more earthy, require more discipline. For instance, there is the commandment that Jewish males be circumcised on the eighth day after birth. In one of those fascinating bits of speculation, the rabbis of the Talmud asked why the penis is circumcised and not another part of a man's body. Circumcision is known as the mark of the covenant, a sign that the male has assumed the burden of Mosaic law.
