Mistress

A mistress is a special girlfriend to a man that is married and has a wife. Mistresses can be more expensive than a wife, but a wife who knows you have a mistress is most expensive. Generally, a man will pay for the expenses of a mistress, such as rent and clothing, jewels, and other things that will keep her happy to not wear a diamond wedding ring.

A wife who no longer wants sex with her husband is more accepting of him having a mistress. She may desire a gigolo.
