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.[1] These terms no longer apply with any accuracy as psychological or legal categories of psychological disorder.[1]
