There is no specific word in English for a “male mistress”, a man in the same relationship to a woman as a mistress is to a man, except for the more general term “lover”, which does not carry the same implications. “Paramour” is sometimes used, but this term can apply to either partner in an illicit relationship, so it is not exclusively male. In 18th- and 19th-century Venice, the terms cicisbeo and cavalier servente were used to describe a man who was the professed gallant and lover of a married woman. Another word that has been used for a male mistress is gigolo, though this carries connotations of payment and prostitution. Since the late 20th century, the terms “Pool boy,” “Fitness trainer” or “Tennis instructor,” were each used to designated males in the role, with the implication of lower social status, youth, and physical fitness leading to a financial relationship to the wealthier married woman.
