What is "chronophilia"

n. Primary or exclusive sexual attraction toward members of a specific age group, as with paedophilia or gerontophilia.

The term chronophilia was used by John Money to describe a form of paraphilia in which an individual experiences sexual attraction limited to individuals of particular age ranges. The term has not been widely adopted by sexologists, who instead use terms that refer to the specific age range in question. An arguable historical precursor was Richard von Krafft-Ebing's concept of "age fetishism".
