EphebophiliaEphebophilia is the primary sexual interest in mid-to-late adolescents, generally ages 15 to 19. 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 is not a psychiatric diagnosis.
PedophiliaPedophilia (alternatively spelled paedophilia) is a psychiatric disorder in which an adult or older adolescent experiences a primary or exclusive sexual attraction to prepubescent children. Although girls typically begin the process of puberty at age 10 or 11, and boys at age 11 or 12, psychiatric diagnostic criteria for pedophilia extend the cut-off point for prepubescence to age 13. Pedophilia is a paraphilia. In recent versions of formal diagnostic coding systems such as the DSM-5 and ICD-11, "pedophilia" is distinguished from "pedophilic disorder.
SexologySexology is the scientific study of human sexuality, including human sexual interests, behaviors, and functions. The term sexology does not generally refer to the non-scientific study of sexuality, such as social criticism. Sexologists apply tools from several academic fields, such as anthropology, biology, medicine, psychology, epidemiology, sociology, and criminology. Topics of study include sexual development (puberty), sexual orientation, gender identity, sexual relationships, sexual activities, paraphilias, and atypical sexual interests.
ParaphiliaParaphilia is the experience of recurring or intense sexual arousal to atypical objects, situations, fantasies, behaviors, or individuals. It has also been defined as a sexual interest in anything other than conventional sexual intercourse with a consenting human partner. The exact number and taxonomy of paraphilia is under debate; one source lists as many as 549 types of paraphilia. Several sub-classifications of paraphilia have been proposed, although some argue that a fully dimensional, spectrum or complaint-oriented approach would better reflect the evident diversity of human sexuality.
