atypical arousal) which indicates a definite preference for animals over humans as sexual partners. Although Krafft-Ebing also coined the term zooerasty for the paraphilia of exclusive sexual attraction to animals, . Zoosexuality The term zoosexual was proposed by Hani Miletski in 2002 as a value-neutral term. Usage of zoosexual as a noun (in reference to a person) is synonymous with zoophile, while the adjectival form of the word – as, for instance, in the phrase "zoosexual act" – may indicate sexual activity between a human and an animal. The derivative noun "zoosexuality" is sometimes used by self-identified zoophiles in both support groups and on internet-based discussion forums to designate sexual orientation manifesting as sexual attraction to animals. Bestiality 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, William H. 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 animal's 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. Sexual arousal from watching animals mate is known as faunoiphilia. Extent of occurrence The Kinsey reports of 1948 and 1953 estimated the percentage of people in the general population of the United States 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. Some later writers dispute the figures, noting that the study lacked a random sample in that it included a disproportionate number of prisoners, causing sampling bias. Martin Duberman has written that it is difficult to get a
