Don Juanism

Don Juanism is an archaic psychological descriptive term for a man who is a "seducer of women", and has a desire to have sex with many different partners. The name is derived from the legendary Don Juan of popular fiction. The psychological disorder, satyriasis, is sometimes considered to be synonymous with Don Juanism.

Psychologist Carl Jung believed that Don Juanism was an unconscious desire of a man to seek his mother in every woman he encountered. However, he didn't see the trait as entirely negative; Jung felt that positive aspects of Don Juanism included heroism, perseverance and strength of will.
