Jewish traditions across different eras and regions devote considerable attention to sexuality. Sexuality is the subject of many narratives and laws in the Tanakh (Hebrew Bible) and rabbinic literature. In Judaism, sexuality is viewed as having both positive and negative potential, depending on the context in which it is expressed. Many sources express a positive attitude towards sex between a married couple. On the other hand, sexual activity is also viewed as a grave sin if it is outside of the bounds of permissible behavior.
