few acts in Judaism which one may not perform even to save one's life. The term erva is also used to describe parts of a female considered to be immodest and sexually provocative including a woman's hair, thighs, and singing voice. Arayot include: Incestuous relations Male-male anal intercourse Bestiality Sex with a Jewish woman during her menstrual period (known as niddah) Other isurei bi'ah include: Sexual intercourse between Jews and Gentiles Divorcees or female converts with Kohanim (priests) Mamzerim (offspring of adulterous unions) with regular Jews When two people are forbidden from having sex together, the laws of negiah prohibit them from engaging in lesser sexual touch (including hugging and kissing), while the laws of yichud prohibit them from spending time together in private in a manner that would allow them to have sex undetected.
