Masters (1962) says that some brothel madams used to stage exhibitions of animals mating, as they found it aroused potential clientele, and that this may have encouraged the clients to engage in bestiality.Zoophilia has been partly discussed by several sciences: Psychology (the study of the human mind), sexology (a relatively new discipline primarily studying human sexuality), ethology (the study of animal behavior), and anthrozoology (the study of human-animal interactions and bonds).However, a number of the most oft-quoted studies, such as Miletski, were not published in peer-reviewed journals.There have been several significant modern books, from Masters (1962) to Beetz (2002); "The phenomenon of sexual contact with animals is starting to lose its taboo: it is appearing more often in scholarly publications, and the public are being confronted with it, too.[...] Sexual contact with animals – in the form of bestiality or zoophilia – needs to be discussed more openly and investigated in more detail by scholars working in disciplines such as animal ethics, animal behavior, anthrozoology, psychology, mental health, sociology, and the law." More recently, research has engaged three further directions – the speculation that at least some animals seem to enjoy a zoophilic relationship assuming sadism is not present, and can form an affectionate bond.
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.
It may also be touched upon by sociology which looks both at zoosadism in examining patterns and issues related to sexual abuse and at non-sexual zoophilia in examining the role of animals as emotional support and companionship in human lives, and may fall within the scope of psychiatry if it becomes necessary to consider its significance in a clinical context. 18, February 2011) states that sexual contact with animals is almost never a clinically significant problem by itself; Additionally, zoophiles in categories 2, 3, and 8 (romantic zoophiles, zoophilic fantasizers, and regular zoophiles) are the most common, while zoophiles found in categories 6 and 7 (sadistic bestials and opportunistic zoophiles) are the least common.
Zoophilia may reflect childhood experimentation, sexual abuse or lack of other avenues of sexual expression.
The terms are often used interchangeably, but some researchers make a distinction between the attraction (zoophilia) and the act (bestiality).
Three key terms commonly used in regards to the subject — zoophilia, bestiality, and zoosexuality — are often used somewhat interchangeably.
Confusing the matter yet further, writing in 1962, Masters used the term bestialist specifically in his discussion of zoosadism.
