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. Confusing the matter yet further, writing in 1962, Masters used the term bestialist specifically in his discussion of zoosadism.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. Colin J. Williams and Martin Weinberg studied self-defined zoophiles via the internet and reported them as understanding the term zoophilia to involve concern for the animals welfare, pleasure, and consent, as distinct from the self-labelled zoophiles concept of "bestialists", whom the zoophiles in their study defined as focused on their own gratification. Williams and Weinberg also quoted a British newspaper saying that zoophilia is a term used by "apologists" for bestiality. Extent of occurrence
The Kinsey reports rated the percentage of people in the general population who had at least one sexual interaction with animals as 8% for males and 5.1% for females (1.5% for pre-adolescents and 3.6% for post-adolescents females), and claimed it was 40–50% for the rural population and even higher among individuals with lower educational status, but some later writers dispute the figures, because the study lacked a random sample in that it included a disproportionate number of prisoners, causing sampling bias.
Similar restrictions apply in Germany (see above). In New Zealand the possession, making or distribution of material promoting bestiality is illegal. The potential use of media for pornographic movies was seen from the start of the era of silent film. Polissons and Galipettes (re-released 2002 as "The Good Old Naughty Days") is a collection of early French silent films for brothel use, including some animal pornography, dating from around 1905 – 1930. Material featuring sex with animals is widely available on the Internet. An early film to attain great infamy was "Animal Farm", smuggled into Great Britain around 1980 without details as to makers or provenance. The film was later traced to a crude juxtaposition of smuggled cuts from many of Bodil Joensens 1970s Danish movies. Today, in Hungary, where production faces no legal limitations, zoophilic materials have become a substantial industry that produces a number of films and magazines, particularly for Dutch companies such as Topscore and Book & Film International, and the genre has stars such as "Hector", a Great Dane dog starring in several films. In Japan, animal pornography is used to bypass censorship laws, often featuring models performing fellatio on animals, because oral penetration of a non-human penis is not in the scope of Japanese pixelization censorship. While primarily underground, there are a number of animal pornography actresses who specialize in bestiality movies.
