Don Juan, for one, is a legendary figure known for his romantic conquests and seductive behavior. He is often referred to as a SEDUCER, ROUE, or LIBERTINE. A SEDUCER is someone who entices another person, usually of the opposite sex, into a sexual relationship. A ROUE is a man who leads a dissolute lifestyle, especially one involving a great deal of promiscuity. A LIBERTINE is someone who lives without moral restraint, often engaging in sexual activity outside of marriage.
