Whoever has cohabitation with a harlot, will request for a Kikar of bread and will not attain it
(Sotah 4A)
This is measure for measure.
A woman is compared to bread-as it says in Chazal, all the Blessings in the house come because of the wife.
A harlot is called a ????. which means wage, which is interchangeable with bread. As all the harlot is interested is in the wage not the intercourse.
So Midah Kneged Middah, the man who has intercourse with a Harlot loses his bread.
