Why is sex pleasurable for humans

Interestingly, although all of these animals have been documented to play with themselves, it is exceedingly rare that they actually get off. Even though the evolution-related purpose of mating can be said to be reproduction, it is not actually the creating of offspring which originally causes them to mate. New reproductive technologies have meanwhile separated sex and reproduction: Its secretion affects the nature of the relationship or if there will even be a relationship at all. Masturbation in horses is also quite common. Clownfish are sequential hermaphrodites, meaning that they develop into males first, and when they mature, they become females. It would be like staring at a painting with half the colour spectrum removed from it. Koinophilia Koinophilia is the love of the "normal" or phenotypically common from the Greek, koinos, meaning "the usual" or "common". Bateman's principle Mating grey slugs , suspended from a slime thread Female and male sexual behaviour differ in many species. Two examples of systems in primates are promiscuous mating chimpanzees and bonobos. We are animals. Von Haartman specifically described the mating behaviour of the European pied flycatcher as successive polygyny. How do we know what feels good to an animal? Prairie voles have a greater number of oxytocin and vasopressin receptors compared to montane voles, and are therefore more sensitive to those two neurohormones. Polygamy in both sexes has been observed in red flour beetle Tribolium castaneum. Besides humans and dolphins, other mammals such as certain monkeys have sex too. This hypothesis about sex has been tested. Why are people and dolphins the only mammals that have sex for pleasure? Most animals cannot afford to waste the energy that is put into the sexual act unless it leads to the production of offspring. Many socially monogamous species engage in extra-pair copulations , making them sexually non-monogamous. As a consequence, the mother rat solicits males to the nest but simultaneously becomes aggressive towards them to protect her young. Many researchers have described homosexuality as something altogether different from sex. The question of whether non-human animals enjoy it too is a perennial — and scientifically legitimate — question to ask. We self-reflect and ponder the future. Bonobos get it on year round as well. As such, polygamous relationships can be polygynous, polyandrous or polygynandrous. Barash and Lipton note: Why is sex pleasurable for humans



Oral sex is also well known among short-nosed fruit bats , for whom it is thought to prolong copulation, thereby increasing the likelihood of fertilisation. One indication that animals enjoy sexual activity is the act of masturbation. It is probable that in these animals, the use of sex evolved beyond reproduction to serve additional social functions. In fact, a lot of animals go solo. A combination of terms indicates examples where levels of relationships coincide, e. Could it be that she enjoys it? Likewise, sexual behaviour can be wholly enjoyable while also emerging from a deeper developmental or evolutionary origin. 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? In a small number of species, individuals can display either polygamous or monogamous behaviour depending on environmental conditions. There is debate as to whether female primates including humans experience sexual pleasure in the same way male primates do, which raises some fairly important questions about how Western culture views female sexual agency. And not only that, they would actively seek out the feeling. In a third of those copulations, they observed what they called female orgasmic responses: Bonobos definitely have sex for fun. The remaining males will move up a rank in the hierarchy. Polyandry in nature Polyandry occurs when one female gets exclusive mating rights with multiple males. In the last 10 to 15 years, scientific evidence has begun to accumulate that animals do experience a general sensation of pleasure — as anybody who has stroked a cat will know. If the female clownfish is removed from the group, such as by death, one of the largest and most dominant males will become a female. It may be the case that what sets us apart is our ability to write, produce, edit, and even star in our own mental porn.

For instance, the clitoris acts in the same way as with women, and scientific studies have shown that the success of reproduction is improved by stimulation of clitoris on among other species cows and mares in connection with insemination, because it improves the transportation of the sperm due to contractions of the inner genitalia. This breeding season is accentuated in temperate regions, in boreal climate the breeding season is typically concentrated to a few short days in the spring. In some species of planarians , sexual behaviour takes the form of penis fencing. Stimuli causing induced ovulation include the sexual behaviour of coitus, sperm and pheromones. This often occurs when the animals are establishing dominance relationships and are not necessarily sexually motivated. But genetic monogamy is strikingly low in other species. Both explanations are probably true, depending on whether you take an expansive, zoomed-out perspective, or a more immediate, zoomed-in perspective. During these periods, females of most mammalian species are more mentally and physically receptive to sexual advances, a period scientifically described as estrous but commonly described as being "in season" or "in heat". In a small number of species, individuals can display either polygamous or monogamous behaviour depending on environmental conditions. And same-sex sexual behavior, which is definitionally non-reproductive, occurs in every vertebrate species in which it has been looked for, along with some non-vertebrates bedbugs, for example, or fruit flies. The numbers of males and females need not be equal, and in vertebrate species studied so far, there are usually fewer males. This view is considered a misconception by some scholars. Polygamy is also seen in many Lepidoptera species including Mythimna unipuncta true armyworm moth. Porcupines have even been witnessed to fashion vibrators out of sticks. A hypothesis suggests these slugs may be able to compensate the loss of the male function by directing energy that would have been put towards it to the female function. One indication that animals enjoy sexual activity is the act of masturbation. Oral sex is also well known among short-nosed fruit bats , for whom it is thought to prolong copulation, thereby increasing the likelihood of fertilisation. Male dogs will pretty much hump anything they can wrap their legs around. Click Here to return to the search form. This is the case with most primates who are primarily tropical and subtropical animals. As the level of oxytocin increases so does sexual motivation. We are doing something that is almost uniquely human. Pheromone -based spontaneous abortion in some rodents such as mice , a new male with a different scent will cause females who are pregnant to spontaneously fail to implant recently fertilised eggs. Many researchers have described homosexuality as something altogether different from sex. In this form of copulation, the individual that first penetrates the other with the penis, forces the other to be female, thus carrying the majority of the cost of reproduction. But some detailed studies of the stump-tailed macaque have suggested that females of this species, at least, demonstrate a capacity for orgasm. Technically, polygyny in sociobiology and zoology is defined as a system in which a male has a relationship with more than one female, but the females are predominantly bonded to a single male.

Female cheetahs and lions lick and rub the males' genitals as a part of their courtship ritual. They probably do it because it feels good. In areas with continuously high primary production , some species have a series of breeding seasons throughout the year. It is probable that they mate because they are motivated for the actual copulation, and because this is connected with a positive experience. It appears as though this is almost true, depending again on how one defines sex for pleasure. Often, males are more active in initiating mating, and bear the more conspicuous sexual ornamentation like antlers and colourful plumage. Oxytocin and rat sexual behaviour[ edit ] Mother rats experience a postparum estrus which makes them highly motivated to mate. In hermaphroditic animals, the costs of parental care can be evenly distributed between the sexes, e. The hypothesis that all sexually reproducing species experience sexual pleasure is, in itself, quite reasonable — as would be the hypothesis that animals find eating pleasurable. Having said that, we can make educated guesses about whether sex is pleasurable for other species. Some species, such as the Rana Clamitans green frog , spend from June to August defending their territory. A female lion may mate times per day over a period of about a week, and with multiple partners, each time she ovulates. The highest known frequency of extra-pair copulations are found among the fairy-wrens , lovely tropical creatures technically known as Malurus splendens and Malurus cyaneus. We have medicine. In a third of those copulations, they observed what they called female orgasmic responses: In fact, a lot of animals go solo. Besides humans and dolphins, other mammals such as certain monkeys have sex too. What makes us so different that our masturbatory experiences are "goal-oriented" when other animals' are not? As a consequence, the mother rat solicits males to the nest but simultaneously becomes aggressive towards them to protect her young. As such, polygamous relationships can be polygynous, polyandrous or polygynandrous. Birds, walruses, sheep, turtles, elephants, bears, and many more species have been observed engaging in autoeroticism. It persisted for years, even after the bears aged out of cub-hood, perhaps because it remained pleasurable and satisfying. And why is our masturbation frequency significantly higher than that of other species? They can no longer assume social monogamy determines how genes are distributed in a species. Jesse Bering hypothesizes that it is because humans have the unique ability to form mental representations of erotic material. An example is the social wasp Apoica flavissima.

We procreate. It is therefore reasonable to assume that there is some form of pleasure or satisfaction connected with the act. This often occurs when the animals are establishing dominance relationships and are not necessarily sexually motivated. Oral sex also occurs with some frequency throughout the animal kingdom. Why are people and dolphins the only mammals that have sex for pleasure? Clownfish are sequential hermaphrodites, meaning that they develop into males first, and when they mature, they become females. Upon withdrawal of a cat's penis , the spines rake the walls of the female's vagina , which may cause ovulation. Domestic cats have penile spines. To prevent this, many female primates exhibit ovulation cues among all males, and show situation-dependent receptivity. But genetic monogamy is strikingly low in other species. We have sex for pleasure significantly more often than we have sex for reproductive purposes. Why is sex pleasurable for humans



Polygyny in animals Polygyny occurs when one male gets exclusive mating rights with multiple females. This female is trailing the atrophied remains of males she has encountered. They probably do it because it feels good. Thinkstock The most instructive example may come from a study of two captive male brown bears published earlier this year in the journal Zoo Biology. Click Here to return to the search form. Male dogs will pretty much hump anything they can wrap their legs around. The issue here is what, if any, neural states in our physical brain lead us to have subjective experiences in our mind, which are called qualia by many people in the field of cognitive science. As a consequence, the mother rat solicits males to the nest but simultaneously becomes aggressive towards them to protect her young. Pheromone -based spontaneous abortion in some rodents such as mice , a new male with a different scent will cause females who are pregnant to spontaneously fail to implant recently fertilised eggs. In some species of planarians , sexual behaviour takes the form of penis fencing. The actual incidence of social monogamy varies greatly across different branches of the evolutionary tree. Porcupines have even been witnessed to fashion vibrators out of sticks. Evolution of monogamy Monogamy occurs when one male mates with one female exclusively. Technically, polygyny in sociobiology and zoology is defined as a system in which a male has a relationship with more than one female, but the females are predominantly bonded to a single male.

Current research frequently expresses views such as that of the Natural History Museum at the University of Oslo , which in held an exhibition on animal sexuality: Parental investment and reproductive success[ edit ] Main article: Copulation zoology Copulation is the union of the male and female sex organs , the innate sexual activity specifically organized to transmit male sperm into the body of the female. Having said that, we can make educated guesses about whether sex is pleasurable for other species. Polygamy in both sexes has been observed in red flour beetle Tribolium castaneum. View image of Getty Images Credit: It is therefore reasonable to assume that there is some form of pleasure or satisfaction connected with the act. We are doing something that is almost uniquely human. Studies[ citation needed ] on the brains of these two species have found that it is two neurohormones and their respective receptors that are responsible for these differences in mating strategies. 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. Polyandry in nature Polyandry occurs when one female gets exclusive mating rights with multiple males. Mammals[ edit ] Mating seasons are often associated with changes to herd or group structure, and behavioural changes, including territorialism amongst individuals. Male prairie voles release vasopressin after copulation with a partner, and an attachment to their partner then develops. Careful analysis must be made to interpret what animal motivations are being expressed by those behaviours. They engage in sex because they're biologically driven to do so, and if the fulfillment of their urges produces a physical sensation we might "pleasure," it isn't the least bit affected by the possibility or impossibility of producing offspring. In a small number of species, individuals can display either polygamous or monogamous behaviour depending on environmental conditions. These species live in social groups consisting of several males and several females.

It's believed[ by whom? The claim that dolphins have sex for pleasure is true for a very specific definition of "sex for pleasure," which is copulation between the male and female of a species not for the purpose of reproduction. For most animals, it seems that there is no biological advantage in engaging in sex when there is no possibility that their genes will be passed through the production of offspring. In humans, social monogamy takes the form of monogamous marriage. Neither male nor female montane voles release high quantities of oxytocin or vasopressin when they mate. They probably do it because it feels good. What makes us so different that our masturbatory experiences are "goal-oriented" when other animals' are not? We self-reflect and ponder the future. Why are people and dolphins the only mammals that have sex for pleasure? Over the course of six years, researchers amassed hours of behavioural observations, which included 28 acts of oral sex between the two bears , who lived together in an enclosure at a sanctuary in Croatia. Mammals[ edit ] Mating seasons are often associated with changes to herd or group structure, and behavioural changes, including territorialism amongst individuals. Most polygamous species present high levels of tournament behaviour, with a notable exception being bonobos [ citation needed ]. 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. Thus, females are more limited in their potential reproductive success. There's even a seminal no pun intended paper on squirrel masturbation.

Your question gets at the heart of what many cognitive scientists in the fields of neuroscience, philosophy, and computer science are trying to address. So the next time I hear somebody quote the Nine Inch Nails song Closer, I'll remember that I'd rather do it like a human, thank you very much. Evolution of monogamy Monogamy occurs when one male mates with one female exclusively. Often, males are more active in initiating mating, and bear the more conspicuous sexual ornamentation like antlers and colourful plumage.

  1. What makes us so different that our masturbatory experiences are "goal-oriented" when other animals' are not? Often, males are more active in initiating mating, and bear the more conspicuous sexual ornamentation like antlers and colourful plumage.

  2. The male then slowly atrophies , losing first his digestive organs, then his brain, heart, and eyes, ending as nothing more than a pair of gonads , which release sperm in response to hormones in the female's bloodstream indicating egg release. There is also no shortage of examples where non-human sex has nothing to do with reproduction at all.

  3. Most animals cannot afford to waste the energy that is put into the sexual act unless it leads to the production of offspring.

  4. The actual incidence of social monogamy varies greatly across different branches of the evolutionary tree. 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.

  5. For these species, the female ovulates due to an external stimulus during, or just prior, to mating, rather than ovulating cyclically or spontaneously. This is sometimes stated as "animals mate only for reproduction". But, as they have been apt to do lately, our favorite ape relatives , the bonobos, have to be included in this conversation.
