Judaism is generally very positive about sex, regarding it as a divine gift and a holy obligation — both for the purposes of procreation and for pleasure and intimacy. The Talmud specifies not merely that a husband is required to be intimate with his wife, but sources also indicate that he is obliged to sexually satisfy her. Instead, sexual activity is highly circumscribed in Jewish tradition, as the rabbis of the Talmud sought to use the human libido as a tool for increasing the population and strengthening marriage. Traditional Jewish law not only prohibits many types of sexual relationships, but it also dictates specific parameters even for permitted ones. And while Judaism is broadly permissive when it comes to sex between married adults, the same is not true for sexual activity outside of a committed relationship. Adultery — traditionally defined as sexual intercourse between a married woman and a man who is not her husband — is forbidden in the seventh of the Ten Commandments and is among the most serious infractions in Judaism.
