Sex, we are told, is pleasurable. That's because most scientific accounts of sexual behaviour rest animal evolutionary explanations rather than the more immediately relevant mental and emotional experiences.

To say that we have sex because it helps us to preserve our genetic legacies would sex entirely accurate, but the more fleeting, experiential, pleasurable aspects of that most basic of social urges would be missing. It would be like staring at a painting with half the colour spectrum removed from it. One thing we have been curious about, though, is whether we are the only species that experiences sexual pleasure. The question of whether non-human animals enjoy it too is a perennial — and scientifically legitimate — question to ask.

In the last 10 to 15 years, scientific animal has begun to accumulate that animals do experience a general sensation of pleasure — as anybody who has animal a cat will know. Infor example, psychologists Jeffrey Burgdorf and Jaak Panskepp discovered that laboratory rats enjoyed being tickledemitting a sort of chirpy laugh outside the range of human hearing.

And not only that, they would actively seek out the feeling. We know animals like cats experience a general sensation of pleasure, but does this extend to sex? But does that include carnal pleasure too? One way to find out is to study instances of sex that can't possibly result in procreation — for instance, among two or more males, or females; where one or more individual is sexually immature, or sex that occurs outside of the breeding season.

Bonobosfor example, the so-called "hippie apes," are known for same-sex interactions, and for interactions between mature individuals animal sub-adults or juveniles. But you don't need to be a bonobo to enjoy "non-conceptive" sex, white-faced capuchin monkeys do it too. In both species, primatologists Joseph Manson, Susan Perry, and Amy Parish, found that that females' solicitation of animal was decoupled from their fertility.

In other words, they had plenty of sex even when pregnancy was impossible — such as when they were already pregnant, or while lactating just following birth. In addition, interactions among mature and immature individuals were just as common as sex between two adults, for both species. If animals indulge in more sex than is strictly necessary for conception, that too might hint at a pleasure-driven motivation to do the deed. A female lion may mate animal per day over a period of about a week, and with multiple partners, each time she ovulates.

It only takes one eager sperm to begin the road from conception to birth, but the lioness sex seem to mind. Could sex be that she enjoys it? Similarly high rates of encounters have been observed among cougars and leopards, too. Researchers have been studying the wide and varied interactions that bonobos take part in for many years Getty Images.

While it's impossible to sex a female macaque to interrogate her feelings, it is reasonable to infer that this behaviour is similar to that experienced by human women, at least in some ways. That's in part because this macaque behaviour is sometimes accompanied by the type of physiological changes seen in humans, such as increases in heart rate and vaginal spasms.

Interestingly, the female macaques were more likely to experience a response when copulating with a male who lived higher-up in their monkey dominance hierarchy, suggesting that there is a social, not just physiological, component to this, not simply a reflexive responses to sexual sex. Oral sex also occurs with some frequency animal the animal kingdom. It's been observed in primates, animal hyenas, goats and sheep.

Female cheetahs and lions lick and rub the males' genitals as a part of their courtship ritual. Oral sex is also well sex among short-nosed fruit sexfor whom it is thought to prolong copulation, thereby increasing the likelihood of fertilisation.

In short-nosed fruit bats, oral sex is thought to help increase the likelihood of fertilisation Thinkstock. The researchers, led by Agnieszka Sergiel of the Polish Academy of Sciences Department of Wildlife Conservation, suspect that the behaviour began as a result of early deprivation of suckling behaviour, since both bears were brought to the sanctuary as orphans, before they were fully weaned from their absentee mothers.

It persisted for years, even after the bears aged out of cub-hood, perhaps because it remained pleasurable and satisfying. In most cases, researchers rely on evolutionary mechanisms to explain such animal behaviour, to resist the pull of anthropomorphosis.

As ethologist Jonathan Balcombe writes in Applied Animal Behaviour Science : "Pain's unpleasantness helps steer the animal away from 'bad' behaviours that risk the greater evolutionary disaster of death. Similarly, pleasure encourages animals to behave in 'good' ways, such as feeding, mating, and…staying warm or cool. Could the urge in animals and humans to vary things in diet be because there's an in-built desire to try new sex Likewise, sexual behaviour can be wholly enjoyable while also emerging from a deeper developmental or evolutionary origin.

It is precisely because reproduction is so important to the survival of a species that evolution made it so pleasurable that animals — both human and non-human — are motivated to seek it out even when conception is undesirable or impossible. The urge to seek out that sort of pleasure, writes Balcombe, "is a combination of instinct on the one hand, and a powerful desire to attain reward on the other.

Another way you might learn whether non-human animals derive pleasure is whether they have orgasms. That's especially true for females, since conception does not rely on their ability to experience one. Italian researchers Alfonso Troisi and Monica Carosi spent hours watching Japanese macaquesand witnessed individual copulations between males and females.

In a third of those copulations, they observed what they called female orgasmic responses: "the female turns her head to look back at animal partner, sex back with one hand, and grasps the male. The most instructive example may come from a study of two captive male brown bears published earlier this year in the journal Zoo Biology. Over the course of six years, researchers amassed hours of behavioural observations, which included 28 acts of oral sex between the two bearswho lived together in an enclosure at a sanctuary animal Croatia.

He goes on to explain that rats prefer unfamiliar foods after three days in which they're only given a single type of food to eat. The simplest explanations for that pattern suggest that the rats' behaviour is adaptive because a diversity of foods allows them to ingest a wider range of nutrients, or maybe because it allows them to avoid overdependence on a possibly limited food source.

But is that too narrow a view, when it's equally plausible that the rats just became bored with their food and wanted to try something new? To spice things up a bit? Both explanations are probably true, depending on whether you take an expansive, zoomed-out perspective, or a more immediate, zoomed-in perspective. Read more. Open share tools. Like us on Facebook.

By , the farm population in the USA had declined by 80 percent compared with , reducing the opportunity to live with animals; Hunt's study suggests that these demographic changes led to a significant change in reported occurrences of bestiality. The percentage of males who reported sexual interactions with animals in was 4. Miletski believes this is not due to a reduction in interest but merely a reduction in opportunity. Nancy Friday 's book on female sexuality , My Secret Garden , comprised around fantasies from different women; of these, 23 involve zoophilic 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.

Sexual arousal from watching animals mate is known as faunoiphilia. Sexual fantasies about zoophilic acts can occur in people who do not have any 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.

Masters 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. Several studies have found that women show stronger vaginal responses to films depicting bonobo copulation than to non-sexual stimuli.

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. The World Health Organization takes the same position, listing a sexual preference for animals in its ICD as "other disorder of sexual preference".

Zoophilia may also be covered to some degree by other fields such as ethics, philosophy, law, animal rights and animal welfare. 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.

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. Exclusive desire for animals rather than humans is considered a rare paraphilia, and sufferers often have other paraphilias [35] with which they present.

Zoophiles will not usually seek help for their condition, and so do not come to the attention of psychiatrists for zoophilia itself. The first detailed studies of zoophilia date from prior to Peer reviewed research into zoophilia in its own right started around 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 to Beetz ; [37] their research arrived at the following conclusions:. 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.

Miletski notes that information on sex with animals on the internet is often very emphatic as to what the zoophile believes gives pleasure and how to identify what is perceived as consent beforehand. For instance, Jonathan Balcombe says animals do things for pleasure. But he himself says pet owners will be unimpressed by this statement, as this is not news to them.

She says only a few recent studies have taken data from volunteers in the community. Medical research suggests that some zoophiles only become aroused by a specific species such as horses , some zoophiles become aroused by multiple species which may or may not include humans , and some zoophiles are not attracted to humans at all.

Researchers who observed a monkey trying to mate with a deer in interspecies sex said that it may provide clues into why humans have interspecies sex. Instances of this behavior have been found in the Bible. Raymond Christinger interprets that as a show of power of a tribal chief, [50] and so we do not know if this practice was then more acceptable, and if the scene depicted was usual or unusual or whether it was symbolic or imaginary.

Potters seem to have spent time depicting the practice, but this may be because they found the idea amusing. Pindar, Herodotus, and Plutarch claimed the Egyptians engaged in ritual congress with goats. Bestiality was accepted in some North American and Middle Eastern indigenous cultures. Several cultures built temples Khajuraho , India or other structures Sagaholm , barrow , Sweden with zoophilic carvings on the exterior, however at Khajuraho these depictions are not on the interior, perhaps depicting that these are things that belong to the profane world rather than the spiritual world, and thus are to be left outside.

In the Church-oriented culture of the Middle Ages zoophilic activity was met with execution, typically burning, and death to the animals involved either the same way or by hanging, as "both a violation of Biblical edicts and a degradation of man as a spiritual being rather than one that is purely animal and carnal.

As with all accusations and confessions extracted under torture in the witch trials in Early Modern Europe , their validity cannot be ascertained. Passages in Leviticus 18 Lev "And you shall not lie with any beast and defile yourself with it, neither shall any woman give herself to a beast to lie with it: it is a perversion. If a woman approaches any beast and lies with it, you shall kill the woman and the beast; they shall be put to death, their blood is upon them.

However, the teachings of the New Testament have been interpreted by some as not expressly forbidding bestiality. In Part II of his Summa Theologica , medieval philosopher Thomas Aquinas ranked various "unnatural vices" sex acts resulting in "venereal pleasure" rather than procreation by degrees of sinfulness, concluding that "the most grievous is the sin of bestiality.

There are a few references in Hindu scriptures to religious figures engaging in symbolic sexual activity with animals such as explicit depictions of people having sex with animals included amongst the thousands of sculptures of "Life events" on the exterior of the temple complex at Khajuraho.

The depictions are largely symbolic depictions of the sexualization of some animals and are not meant to be taken literally.

In many jurisdictions, all forms of zoophilic acts are prohibited; others outlaw only the mistreatment of animals, without specific mention of sexual activity. In the United Kingdom, Section 63 of the Criminal Justice and Immigration Act also known as the Extreme Pornography Act outlaws images of a person performing or appearing to perform an act of intercourse or oral sex with an animal whether dead or alive.

Nor is it a question of the sexual arousal of the defendant", [67] "it could be argued that a person might possess such an image for the purposes of satire, political commentary or simple grossness," according to The Independent. Many new laws banning sex with animals have been made recently, such as in New Hampshire , [69] Ohio , [ citation needed ] Germany , [70] Sweden , [71] Denmark , [72] Thailand , [73] Costa Rica , [74] Bolivia , [75] and Guatemala.

Laws on zoophilia are sometimes triggered by specific incidents. In the past, some bestiality laws may have been made in the belief that sex with an animal could result in monstrous offspring, as well as offending the community. Current anti-cruelty laws focus more specifically on animal welfare while anti-bestiality laws are aimed only at offenses to community "standards".

The agency believed current animal cruelty legislation was not sufficient in protecting animals from abuse and needed updating, but concluded that on balance it was not appropriate to call for a ban. Under Section of the Crimes Act , individuals can serve a sentence of seven years duration for animal sexual abuse and the offence is considered 'complete' in the event of 'penetration'. Some countries once had laws against single males living with female animals, such as Alpacas.

As of , bestiality is illegal in 45 U. Most state bestiality laws were enacted between and After an incident on 2 July , when a man was pronounced dead in the emergency room of the Enumclaw community hospital after his colon ruptured due to having been sodomized by a horse, the farm garnered police attention.

The state legislature of the State of Washington , which had been one of the few states in the United States without a law against bestiality, within six months passed a bill making bestiality illegal. When such laws are proposed, they are never questioned or debated. Pornography involving sex with animals is widely illegal, even in most countries where bestiality itself is not explicitly outlawed. In the United States , zoophilic pornography would be considered obscene if it did not meet the standards of the Miller Test and therefore is not openly sold, mailed, distributed or imported across state boundaries or within states which prohibit it.

Under U. Production and mere possession appears to be legal, however. Extreme Associates a judgement which was overturned on appeal, December 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 as " The Good Old Naughty Days " is a collection of early French silent films for brothel use, including some animal pornography, dating from around — Material featuring sex with animals is widely available on the Internet, due to its ease of production. Another early film to attain great infamy was " Animal Farm ", smuggled into Great Britain around without details as to makers or provenance.

Into the s the Dutch took the lead, creating figures like "Wilma" and the "Dutch Sisters". Many Hungarian mainstream performers also appeared anonymously in animal pornography in their early careers. For example, Suzy Spark. In Japan, animal pornography is used to bypass censorship laws, often featuring Japanese and Swedish [ citation needed ] female models performing fellatio on animals, because oral penetration of a non-human penis is not in the scope of Japanese mosaic censor.

While primarily underground, there are a number of animal pornography actresses who specialize in bestiality movies. In the UK Section 63 of the Criminal Justice and Immigration Act criminalises possession of realistic pornographic images depicting sex with animals see extreme pornography , including fake images and simulated acts, as well as images depicting sex with dead animals, where no crime has taken place in the production.

The law provides for sentences of up to two years in prison; a sentence of 12 months was handed down in one case in Pornography of this sort has become the business of certain spammers such as Jeremy Jaynes and owners of some fake TGPs , who use the promise of "extreme" material as a bid for users' attention.

Infections that are transmitted from animals to humans are called zoonoses. Some zoonoses may be transferred through casual contact, but others are much more readily transferred by activities that expose humans to the semen , vaginal fluids, urine , saliva , feces and blood of animals. Examples of zoonoses are Brucellosis , Q fever , leptospirosis , and toxocariasis.

Therefore, sexual activity with animals is, in some instances, a high risk activity. Allergic reactions to animal semen may occur, including anaphylaxis. Bites and other trauma from penetration or trampling may occur. The love of animals is not necessarily sexual in nature. In psychology and sociology the word "zoophilia" is sometimes used without sexual implications. Being fond of animals in general, or as pets, is accepted in Western society, and is usually respected or tolerated.

However, the word zoophilia is used to mean a sexual preference towards animals, which makes it [] a paraphilia. Some zoophiles may not act on their sexual attraction to animals. People who identify as zoophiles may feel their love for animals is romantic rather than purely sexual, and say this makes them different from those committing entirely sexually motivated acts of bestiality. An online survey which recruited participants over the internet concluded that prior to the arrival of widespread computer networking , most zoophiles would not have known other zoophiles, and for the most part, zoophiles engaged in bestiality secretly, or told only trusted friends, family or partners.

The internet and its predecessors made people able to search for information on topics which were not otherwise easily accessible and to communicate with relative safety and anonymity. Because of the diary-like intimacy of blogs and the anonymity of the internet, zoophiles had the ideal opportunity to "openly" express their sexuality. These groups rapidly drew together zoophiles, some of whom also created personal and social websites and internet forums.

By around —, the wide social net had evolved. Weinberg and Williams observe that the internet can socially integrate an incredibly large number of people. Further, while the farm boys Kinsey researched might have been part of a rural culture in which sex with animals was a part, the sex itself did not define the community.

The zoophile community is not known to be particularly large compared to other subcultures which make use of the internet, so Weinberg and Williams surmised its aims and beliefs would likely change little as it grew.

Those particularly active on the internet may not be aware of a wider subculture, as there is not much of a wider subculture [ clarification needed ] , Weinberg and Williams felt the virtual zoophile group would lead the development of the subculture. There also exist websites which aim to provide support and social assistance to zoophiles including resources to help and rescue abused or mistreated animals , but these are not usually well publicized.

Such work is often undertaken as needed by individuals and friends, within social networks, and by word of mouth. One notable early attempt at creating a zoophile support structure focused on social and psychological support was the newsgroup soc. Zoophiles tend to experience their first zoosexual feelings during adolescence, and tend to be secretive about it, hence limiting the ability for non-Internet communities to form: [].

It was an extension of my affection for the dog and of my discovery of sex. He's a male. I'm a male. I wanted to make him feel good. I definitely knew I wasn't going to be talking to my parents or my friends about this. Because of its controversial nature, people have developed arguments both for [] and against [] zoophilia. Arguments for and against zoosexual activity from a variety of sources, including religious, moral, ethical, psychological, medical and social.

Bestiality is seen by the government of the United Kingdom as profoundly disturbed behavior as indicated by the UK Home Office review on sexual offences in Beetz argues that animals might be traumatized even by a non-violent, sexual approach from a human; [] however, Beetz also says that in some cases, non-abusive bestiality can be reciprocally pleasurable for both the human and non-human animal.

An argument from human dignity is given by Wesley J. Smith, a senior fellow and Intelligent Design proponent at the Center for Science and Culture of the conservative Christian Discovery Institute : — "such behavior is profoundly degrading and utterly subversive to the crucial understanding that human beings are unique, special, and of the highest moral worth in the known universe—a concept known as ' human exceptionalism ' One of the primary critiques of bestiality is that it is harmful to animals and necessarily abusive, because animals are unable to give or withhold consent.

The Humane Society of the United States HSUS has said that as animals do not have the same capacity for thinking as humans, they are unable to give full consent.

The HSUS takes the position that all sexual activity between humans and animals is abusive, whether it involves physical injury or not. Frank Ascione stated that "bestiality may be considered abusive even in cases when physical harm to an animal does not occur.

Some defenders of bestiality argue that the issue of sexual consent is irrelevant because many legal human practices such as semen collection , artificial insemination , hunting, laboratory testing , and slaughtering animals for meat do not involve the consent of the animal.

Such procedures are probably more disturbing physically and psychologically than acts of zoophilia would be, yet the issue of consent on the part of the animal is never raised in the discussion of such procedures.

To confine the 'right' of any animal strictly to acts of zoophilia is thus to make a law [against zoophilia] based not on reason but on moral prejudice, and to breach the constitutional rights of zoophiles to due process and equality before the law.

Miletski believes that "Animals are capable of sexual consent — and even initiation — in their own way. Most people can tell if an animal does not like how it is being petted, because it will move away. An animal that is liking being petted pushes against the hand, and seems to enjoy it. To those defending bestiality this is seen as a way in which animals give consent, or the fact that a dog might wag its tail. Utilitarian philosopher and animal liberation author Peter Singer argues that bestiality is not unethical so long as it involves no harm or cruelty to the animal [] see Harm principle.

In the article "Heavy Petting," [] Singer argues that zoosexual activity need not be abusive, and that relationships could form which were mutually enjoyed. Singer and others have argued that people's dislike of bestiality is partly caused by irrational speciesism and anthropocentrism.

Research has proven that non-human animals can and do have sex for non-reproductive purposes and for pleasure. Some zoophiles claim that they are not abusive towards animals: [98]. Many even consider themselves to be animal welfare advocates in addition to zoophiles. Because of its controversial nature, different countries vary in the discussion of bestiality. Often sexual matters are the subject of legal or regulatory requirement.

In the UK broadcasting regulator OFCOM updated its code stating that freedom of expression is at the heart of any democratic state.

Adult audiences should be informed as to what they will be viewing or hearing, and the young, who cannot make a fully informed choice for themselves, should be protected.

Hence a watershed and other precautions were set up for explicit sexual material, to protect young people. Zoophile activity and other sexual matters may be discussed, but only in an appropriate context and manner. The IPT was replaced after the Films, Videos, and Publications Classification Act in , replaced with bodies designed to allow both more debate and increased consistency, and possession and supply of material that it is decided are objectionable was made a criminal offence.

Philip K. John Irving 's novel The Cider House Rules repeatedly mentions a pornographic photograph depicting oral sex on a pony. In Clerks II Randal orders a donkey show as a going away present for his best friend Dante, in which it is referred to as "interspecies erotica" by the male performer. Pu Songling refers to zoophilia in the Strange Tales from a Chinese Studio short story " The Fornicating Dog ", which talks about sexual relations between a woman and her white dog.

This is of course because offspring get a random mix of genes from their parents. Such variation is a driving force of evolution. Species tend to produce more offspring than the environment can support, and the ones that have beneficial variations survive and pass the genes responsible for them down to their kids. The weak get weeded out, and thus does a species adapt to its environment and its predators.

Sexual reproducers, with their constant mixing of genes, are creating highly varied populations. She burrows into a wasp and pokes her oviduct through its exoskeleton, and the male comes along and fertilizes her.

As the kids grow, they devour their mother from the inside out and erupt from the host. Sometimes sexual reproducers have kids that have a mutation that protects them from a given disease—the offspring with the mutation survive to mate and pass it down the generations. Asexual reproduction is no slouch, though. It's beneficial because it allows creatures to skip the whole fighting-and-possibly-dying-for-the-right-to-mate thing. There are no females who have to put up with males, who quite frankly are a bit of a pain in the ass I would know, as I am one and also a pain in the ass.

Plus, if you can just clone yourself, you can propagate the species without finding a partner. So both options have their ups and downs, but its with sexual reproduction where things get real interesting. If you thought we humans had problems between the sexes, males and females of other species are positively at war.

The problem is competing interests: Males typically want to mate with anything that moves, while females have to be choosier. This is because it's tremendously costly for females to not only produce the eggs, but in the case of mammals, to schlep the young around in their bellies. Males have it easy: They just produce energetically cheap sperm. Females also have to be careful when choosing a mate because they want to ensure their kids get good, strong genes.

This is what asexual reproduction looks like. You're looking at a hydra, a tiny gelatinous creature related to jellyfish, and its adorable little clone. This leads to conflict, such as female ducks evolving that corkscrew vagina. One sex evolves a defense, and the other an offense, delicately balancing so as not to stop breeding altogether. Control over reproduction is great and all, but you still want to be able to propagate the species. There are other reasons, of course.

The male anglerfish, for instance, bites onto a female, fuses to her, and lives the rest of his life as her sperm factory. This is an evolutionary ploy to ensure that when an anglerfish couple manages to meet in the vast emptiness that is the deep sea, they can be damn sure they get some fertilization happening. Some of them just drop dead after they mate, having fulfilled their existential purpose in life: passing along their genes.

Once completed, they peace out. Other times the females will just devour them after sex, known rather epically as sexual cannibalism.

It gives the females a nice little energy boost as they begin developing their young. Such are the eccentricities of making whoopee in the animal kingdom. Sex is weird because sometimes it has to be—it's the price we pay for subscribing to this mode of reproduction. We don't have the luxury of just making copies of ourselves, but by having sex we supercharge the variation of our young.

Sure, sexual reproducers sometimes forfeit limbs or even their lives in the process. That just comes with the territory. Makes that one weird sex trick you do seem pretty prosaic, though, doesn't it? Jason Kehe. Jakob Schiller.
