Although sexual relations with animals are not outlawed in some countries (see the section on legal aspects below), it is not explicitly condoned anywhere. In most countries, such acts are illegal under animal abuse laws or laws dealing with crimes against nature.
Terminology
The term "zoophilia" was introduced into the field of research on sexuality in Psychopathia Sexualis (1886) by Krafft-Ebing, who described a number of cases of "violation of animals (bestiality)", as well as "zoophilia erotica", which he defined as a sexual attraction to animal skin or fur. He used the term zooerasty for the paraphilia of exclusive sexual attraction to animals, but that has fallen out of use.
Zoophilia can refer to sexual activity with animals (bestiality), the desire to do so, or to the paraphilia of the same name which requires a definite preference for animals over humans as sexual partners.
Some zoophiles and researchers draw a distinction between zoophilia and bestiality, using the former to describe the desire to form sexual relationships with animals, and the latter to describe the sex acts alone. Masters (1962) uses the term "bestialist" specifically in his discussion of zoosadism, which refers to deriving sexual pleasure from cruelty to animals. Stephanie LaFarge, an assistant professor of psychiatry at the New Jersey Medical School, and Director of Counseling at the ASPCA, writes that two groups can be distinguished: bestialists, who rape or abuse animals, and zoophiles, who form an emotional and sexual attachment to animals. Williams and Weinberg studied self-defined zoophiles via the internet and found they saw the term as involving concern for the animal's welfare and pleasure, and an emphasis on believing they obtained consent, as opposed to the zoophile's concept of bestialists, who zoophiles defined as a group who focussed only on their own gratification. Williams and Weinberg also quoted a British newspaper as saying that zoophilia is the term used by apologists of bestiality.
The more recent terms "zoosexual" and "zoosexuality" have been used since the 1980s (cited by Miletski, 1999); to refer to a sexual orientation. Pornographers sometimes use the terms "dogsex" and "farmsex."
Ernest Bornemann (1990, cited by Rosenbauer 1997) coined the separate term "zoosadism" for those who derive pleasure from inflicting pain on an animal, sometimes with a sexual component. Some horse-ripping incidents have a sexual connotation.
Extent of occurrence
The Kinsey reports controversially rated the percentage of people who had sexual interaction with animals at some point in their lives as 8% for men and 3.6% for women, and claimed it was 40–50 percent in people living near farms, but some later writers dispute the figures, because the study lacked a random sample, and because the prison population was included, causing sampling bias. Martin Duberman has written that it is difficult to get a random sample in sexual research, and that even when Paul Gebhard, Kinsey's research successor, removed prison samples from the figures, he found the figures were not significantly changed.
By 1974, the farm population in the USA had declined by 80 percent compared to 1940, reducing the opportunity to live with animals; Hunt's 1974 study suggests that the demographic changes led to a significant change in reported occurrence. Males in 1974 were 4.9% (1948: 8.3%), and in females in 1974 were 1.9% (1953: 3.6%). Miletski believes this is not a reduction in interest but a reduction in opportunity.
Nancy Friday's 1973 book on female sexuality, My Secret Garden, comprised around 190 fantasies from different women; of these, 23 involve zoosexual activity.
In one study, psychiatric patients were found to have a statistically-significant higher prevalence rate (55 percent) of reported bestiality, both actual sexual contacts (45 percent) and sexual fantasy (30 percent) than the control groups of medical in-patients (10 percent) and psychiatric staff (15 percent). Crépault and Couture (1980) reported that 5.3 percent of the men they surveyed have fantasized about sexual activity with an animal during heterosexual intercourse. A 1982 study suggested that 7.5 percent of 186 university students had interacted sexually with an animal.
Sexual fantasies about zoosexual acts can occur in people who do not wish to experience them in real life. Nancy Friday notes that zoophilia as a fantasy may provide an escape from cultural expectations, restrictions, and judgements in regard to sex. A frequency interest in and sexual excitement at watching animals mate is cited as an indicator of latent zoophilia by Massen (1994). Masters (1962) says brothel madames used to stage exhibitions of animals mating, as they found it aroused their clientele, and that to some people it can drive them to acts of bestiality.
