אמר רב יהודה אמר רב אנשי ירושלים אנשי שחץ היו אדם אומר לחברו במה סעדת היום בפת עמילה או בפת שאינה עמילה ביין גורדלי או ביין חרדלי במסב רחב או במסב קצר בחבר טוב או בחבר רע א"ר חסדא וכולן לזנות
On the topic of the sins of Jerusalem and the abundance that existed before its destruction, Rav Yehuda said that Rav said: The people of Jerusalem were people of arrogance. They would couch their crude behavior in euphemisms. A person would say to another: On what did you dine today? Well-kneaded bread or bread that is not well-kneaded? On white wine or on black wine? Sitting on a wide divan or on a narrow divan? With a good friend or a bad friend? And Rav Ḥisda said: And all these allude to promiscuity. These are all euphemisms for different types of women. Well-kneaded bread refers to a woman who is not a virgin; white wine refers to a fair-complexioned woman; a wide divan refers to a fat woman; a good friend refers to a good-looking woman.
§ The mishna said that men of leisure must engage in marital relations with their wives every day. The Gemara asks: What is meant by the term men of leisure? Rava said: These are students of Torah who go daily to review their lectures at a local study hall and return home each evening. Abaye said to him: Wives of Torah scholars are those about whom it is written: “It is vain for you to rise early and sit up late, you that eat the bread of toil, so He gives to His beloved in sleep” (Psalms 127:2), and Rabbi Yitzḥak said in explanation of this verse: These are the wives of Torah scholars who deprive their eyes of sleep in this world and reach the life of the World-to-Come.
§ The mishna said: The set interval for laborers to fulfill their conjugal obligations to their wives is twice a week. This is also taught in the Tosefta (5:6): For laborers, twice a week. In what case is this statement said? It is when they work in their own city, but when they work in another city, the set interval for their conjugal obligations is once a week. § The mishna said: The set interval for donkey drivers is once a week, and for other professions it is even less frequent.
the tanna taught us a halakha with regard to all of them, not only a man of leisure or a laborer. He asked him: But with regard to a sailor it said that the set interval for conjugal relations is six months;
Rabba bar Rav Hanan said to Abaye: If a donkey driver who is already married wants to become a camel driver, what is the halakha? Is he permitted to change his profession in order to earn more money from his work, even though this will mean he reduces the frequency with which he engages in conjugal relations with his wife? He answered him: A woman prefers a kav, i.e., modest means, with conjugal relations to ten kav with abstinence. Consequently, he is not allowed to change his profession without her permission.
