What is a male gender if mistress?

The male equivalent of a "mistress" is often referred to as a "mister" or "paramour," though these terms are less commonly used. A mistress typically refers to a woman in a romantic or sexual relationship with someone who is married to another person, while a male counterpart may simply be called a lover or boyfriend in a similar context. The term "gigolo" can also apply, particularly when the male is financially supported by a female partner. However, the social connotations and cultural perceptions may vary significantly between the genders.
