In the late 19th century, psychologists and psychiatrists started to categorize various paraphilias as they wanted a more descriptive system than the legal and religious constructs of sodomy and perversion. Before the introduction of the term paraphilia in the DSM-III (1980), the term sexual deviation was used to refer to paraphilias in the first two editions of the manual. In 1981, an article published in American Journal of Psychiatry described paraphilia as "recurrent, intense sexually arousing fantasies, sexual urges, or behaviors generally involving" the following:
Non-human objects
The suffering or humiliation of oneself or ones partner
Children
Non-consenting persons

Homosexuality and non-heterosexuality
Homosexuality, now widely accepted as a variant of human sexuality, was at one time discussed as a sexual deviation. Sigmund Freud and subsequent psychoanalytic thinkers considered homosexuality and paraphilias to result from psychosexual non-normative relations to the Oedipal complex. As such, the term sexual perversion or the epithet pervert have historically referred to gay men, as well as other non-heterosexuals (people who fall outside the perceived norms of sexual orientation).By the mid-20th century, mental health practitioners began formalizing "deviant sexuality" classifications into categories. Originally coded as 000-x63, homosexuality was the top of the classification list (Code 302.0) until the American Psychiatric Association removed homosexuality from the DSM in 1973. Martin Kafka writes, "Sexual disorders once considered paraphilias (e.g., homosexuality) are now regarded as variants of normal sexuality.
