A Ephebophile is the clinical term for an adult with a primary sexual interest for pubescent adolescents that are in their mid-to-late teens, typically teenagers between the age of 15-19. The term for an adult with a primary sexual interest in younger pubescent children is a Hebephile, the typical age range of their interest is 11-14. Finally the clinical term for an adult with a primary (often exclusive) sexual interest in prepubescent children is a Pedophile, the typical age range of their focus is any child (typically under the age of 10 but not always) who has not yet began puberty. However in common language the term pedophile is used as a slang term for any adult showing a sexual interest in minors under the age of consent.
