Apropos the discussion of the obligation to allow oneself to be killed rather than engage in forbidden sexual intercourse, the Gemara notes that Rav Yehuda says that Rav says: There was an incident involving a certain man who set his eyes upon a certain woman and passion rose in his heart, to the point that he became deathly ill. And they came and asked doctors what was to be done with him. And the doctors said: He will have no cure until she engages in sexual intercourse with him. The Sages said: Let him die, and she may not engage in sexual intercourse with him. The doctors said: She should at least stand naked before him. The Sages said: Let him die, and she may not stand naked before him. The doctors suggested: The woman should at least converse with him behind a fence in a secluded area, so that he should derive a small amount of pleasure from the encounter. The Sages insisted: Let him die, and she may not converse with him behind a fence.
The Gemara asks: But if the woman was unmarried, let the man marry her. The Gemara answers: His mind would not have been eased by marriage, in accordance with the statement of Rabbi Yitzak. As Rabbi Yitzak says: Since the day the Temple was destroyed, sexual pleasure was taken away from those who engage in permitted intercourse and given to transgressors, as it is stated: Stolen waters are sweet, and bread eaten in secret is pleasant (Proverbs 9:17). Therefore, the man could have been cured only by engaging in illicit sexual interaction.
