Autozoophilia

Autozoophilia names sexual arousal at the idea of being an animal, not attraction to real animals as sexual partners. That distinction is the entire point of the concept: it is the self-facing mirror image of zoophilia (attraction to animals), located instead in fantasies of one's own body or identity as non-human. Sexology groups it among the erotic target identity inversions (ETII), a small set of proposed paraphilic dimensions in which arousal is redirected from an external target onto the self. This article covers the theory's origin, the studies that tested it, how the interest is described by those who report it, and where it sits relative to the furry fandom and therian identities it is most often confused with.

Definition & scope

Wikipedia's summary of the erotic target location error framework defines autozoophilia plainly as "sexual arousal in association with being an animal," set against zoophilia, "the sexual preference for animals" as external partners. A closely related, narrower term, autoanthropomorphozoophilia, refers specifically to arousal at being an anthropomorphic animal, a human-like creature such as a fursona, rather than a literal non-human one; the two terms are used somewhat interchangeably in the research literature depending on which population is being studied. Neither term describes attraction to, or conduct involving, real animals, and neither implies any sexual interest in them.

History & origins

From erotic target location error to a testable prediction

The parent concept, the erotic target location error (ETLE), was introduced in 1993 by sexologists Kurt Freund and Ray Blanchard, who proposed that some paraphilias arise when an erotic interest is "mislocated," either onto a peripheral part of a partner or, in its inward form, onto the self. The inward form was later named erotic target identity inversion (ETII) and elaborated by sexologist Anne Lawrence, who catalogued animal-directed arousal (autozoophilia) alongside the better-known autogynephilia (arousal at the fantasy of being a woman) as one of several parallel inversions, each mirroring a corresponding external attraction (see erotic target identity inversion for the full family).

Testing the theory in furries

The first empirical test of ETII theory as a general prediction, that people attracted to any given target should include a subset who are also aroused by fantasizing about being that target, was Kevin Hsu and J. Michael Bailey's 2017 study of men attracted to children, "Autopedophilia: Erotic-Target Identity Inversions in Men Sexually Attracted to Children" (Psychological Science 28(1):115–123). Hsu and Bailey then turned to animal attraction directly in "The 'Furry' Phenomenon: Characterizing Sexual Orientation, Sexual Motivation, and Erotic Target Identity Inversions in Male Furries" (Archives of Sexual Behavior, 2019, 48(5):1349–1369), surveying 334 self-identified male furries online. They reported that sexual attraction to anthropomorphic animals and arousal at fantasizing about being one were both close to universal in the sample, and that the strength of one tracked the strength of the other, the correlational signature ETII theory predicts.

Broader confirmation

A 2020 study by Ashley Brown, Edward Barker and Qazi Rahman, "Erotic Target Identity Inversions Among Men and Women in an Internet Sample" (Journal of Sexual Medicine 17(1):99–110), surveyed 736 men and 549 women and measured autoanthropomorphozoophilia alongside autogynephilia, autoandrophilia and autonepiophilia, finding mild inversion-related arousal fairly common and stronger forms rarer, especially in women. In 2023, Bailey, Hsu and Jang, "Elaborating and Testing Erotic Target Identity Inversion Theory in Three Paraphilic Samples" (Archives of Sexual Behavior 54(8):2805–2823), extended the test to 1,501 men attracted to animals (alongside separate samples attracted to amputees and to severely obese people) and found the correlation between an external attraction and its matching inversion approached 1.0 after statistical correction, read by the authors as strong support for a single shared mechanism rather than two independent interests. Autozoophilia does not appear as a standalone entry in the DSM-5-TR or ICD-11, and is absent from Wikipedia's list of paraphilias as its own heading; it is discussed in the literature as a proposed dimension within ETII theory rather than a diagnosis in its own right.

In practice

Autozoophilia is expressed almost entirely through fantasy, identification and, for some, appearance: imagining being an animal, wearing gear such as a fursuit, or engaging in animal-like behavior in private or role-play contexts. The Brown, Barker and Rahman sample reported behaviors ranging from imagining being a real animal to dressing or acting like one, with a minority also wanting some physical modification toward an animal-like appearance. None of this involves, or requires, a real animal partner.

Psychology

ETII theory frames autozoophilia as an external attraction turned inward, so the self becomes the erotic object rather than an animal partner. Hsu and Bailey's furry data support this by showing the two forms of arousal rising and falling together within the same people rather than appearing independently. The theory remains a hypothesis inferred from self-report surveys of self-selected internet samples, not from biological markers, and it does not establish what causes the pattern. It is also genuinely contested: some researchers argue furry sexuality is better explained by ordinary conditioning onto a fandom's imagery than by an inborn identity inversion, a debate summarized in the broader erotic target identity inversion entry.

Prevalence & culture

No general-population survey has measured autozoophilia, so every figure comes from convenience samples of people already interested in furry or animal-attraction communities, and confidence in any prevalence estimate is low. Within furry-fandom surveys specifically, related but distinct therian identification (feeling, non-sexually, that one is part animal) has run from roughly 5% to 20% of samples, a reminder that identifying with an animal and being sexually aroused by that identification are separate phenomena that only sometimes coincide. Autozoophilia itself has essentially no mainstream cultural visibility and lives almost entirely within academic sexology and the furry community's own internal vocabulary.

Safety, consent & law

Autozoophilia describes private fantasy and self-identification. It is legal and involves no other party, and it is not itself a form of harm; responsible discussion of the concept is careful to keep it separate from zoophilia and bestiality, which involve real animals and are a distinct and, unlike autozoophilia, seriously harmful matter. Where a person experiences genuine distress over the mismatch between their felt and physical identity, that distress, not the fantasy itself, is the appropriate target of any clinical support.
