The first edition of Psychopathia Sexualis (1886) presented four categories of what Krafft-Ebing called “cerebral neuroses”:

paradoxia — sexual desire at the wrong time of life
anesthesia — insufficient sexual desire
hyperesthesia — excessive sexual desire
paraesthesia — misdirected sexual desire (e.g., homosexuality/bisexuality, sexual fetishism, sadism, masochism, and pedophilia)
