Don Juanism
Don Juanism or Don Juan syndrome is a non-clinical term for the desire, in a man, to have sex with many different female partners. The name derives from the Don Juan of opera and fiction. The term satyriasis is sometimes used as a synonym for Don Juanism. The term has also been referred to as the male equivalent of nymphomania in women. Historian Carol Groneman has claimed that these terms no longer apply with any accuracy as psychological or legal categories of psychological disorder.
