The term was originally used in the late 19th to mid-20th century. It is one of a number of sexual preferences across age groups subsumed under the technical term chronophilia. Ephebophilia strictly denotes the preference for mid-to-late adolescent sexual partners, not the mere presence of some level of sexual attraction. It

While individuals with a sexual preference for adults may have some sexual interest in pubescent-aged individuals, researchers and clinical diagnoses have proposed that hebephilia is characterized by a sexual prefe

For instance, whether someone who is sexually attracted to individuals of any age older than their own could be diagnosed or whether the attraction is solely for elderly individuals, remains undecided.
