Why do animals have sex for creation and humans for their desire? Every time an animal have sex they create but humans don't why?

Firstly, humans are animals. Humans are meant to have sex for creation of life. However, society today has changed and it has evolved so that it is acceptable to just have sex for "desire".

I guess you mean mammals, because animals include a wide range of species from paramecium, an unicellular organism to fish, lizard, mankey etc... . so lets talk about mammals: I think mammals are prompted by the desire to have sex and then they create offspring. Biologically speaking, sex is vehicle to get the survival of the species and the group, the tribe or the family. Then, more you have different combination of the genome and more you have chance that your species or your family can survive. The survival instict is so strong that the evolution will select all behaviour or physical characteristics to impose one genome (the strongest) on another one (the weakest). So basically, what I would say that desire to have sex is behaviour selected by the evolution to raise the frequency of creation and the survival of the group. Humans have the same instincts of others mammals but social constraints much much more complexes. Again in humans the same biological laws are applied: what is the chance of survival in, lets say, a western society a family is composed by 12 or 15 offspring? The goal in a mammalian nature is to get a strong genome to have a privelege position in the society. If in a family there are 15 chindren is normally very hard to make a successfull life for all of them. Finally my answer of why humans do not create offspring everytime they have sex is because is evolutionary selected. So they make sex to satisfy the desire to have sex (like eat drink etc) but the natural selection does not want a lot of offspring and the best will continue the genome, but it wants very very strong few offspring. Because the human society in the same way if you think that the juvenile period (imprinting period) of humans is much much longer that the other mammals, meaning a more complex preparation for the society. This question could also be answered from an ecological point of view: once a species reach the overpopulation and there is a limitation of resources, there is a dramatically stop of the proliferation again by biological issues. Of course this is just a point of view of a very very intriguing question!!!!!

With humans, sex is obviously required to have a child of your own( as in ,not adopted or from a test tube), and the sex has the added bonus of pleasure. It's not sinful for a married man & woman to desire each other sexually, in fact, God intended that we should desire to be with our spouse ( of the opposite sex) in that way. A baby does not result from each time either. The world would be REALLY over-populated then. With animals, it's the survival of the fittest among predators, so that's why every time they try, it's likely successful.

I would only add a little to what Dr evol says.
Bonobos and Chimps are human's closest living relatives. Bonobos use sex to settle any disputes they may have. Theirs is a matriarchal society where the females are in control. The males are perfectly happy in this arrangement since they never have to fight each other for sexual favors. The favors are always available and not just from the females. They regularly engage in same sex sex.
No scientist I know of has talked about this, but I suspect the common ancestor of humans and bonobos was already set up for the females to always be receptive to sexual activity and not just during their "fertile" times. We have no way of knowing, of course, but when a trait is in both species, it would seem likely that it was in the ancestor species. Chimps and humans just never quite made it to the females being in charge.

I would say the premise of your question is false.
the human sex "desire" is meant for "creation". WE have just come up with ways to prevent conception.
And not all sex in the rest of the animal kingdom results in a birth.
We are animals too.
Who says animals don't "desire" their partners?
You view is very anthropocentric

Well actually dolphins have been shown to have sex not for procreation but for pleasure only, so humans are not unique in this aspect.
Humans are indeed animals, but we are unique in that we have evolved to be able to go beyond our primary goal in life. The primary goal for any organism is to reproduce and ensure the survival of their genetic material, this is encouraged in humans by the sensation of pleasure experienced during copulation.
Humans have learned to harness this pleasure, and modify the process by which the end result is not always pregnancy, our technology (namely contraception in this instance) has allowed us to escape the bounding to this primary objective.

As pointed out by Melody, humans *are* animals, and we engage in sex for procreation. What we have that NHAs (non-human animals) don't have is the ability to control our reproduction through birth control. More important still, in our species, females *hide* their fertility through the menstrual cycle, something that's fairly unusual among animals (see a couple of my earlier posts on this topic if interested). So human females have evolved to be sexually receptive to males throughout the year via menstruation. This facilitiates pair bonding, and encourages cooperative behaviors in mated pairs of humans (e.g., living together, sharing resources, etc.).
So sex among humans in part evolved as a means of improving the likely survival of offspring through cooperation between mated pairs. It provides for greater resources for the offspring.
That all said, there are a number of NHAs that engage in sex for personal gratification rather than for strictly reproductive purposes. Some one else already mentioned dolphins, which is good. Among primates, Bonobos ("pygmy" chimps) engage in non-reproductive sex more than any species of primate, including us. ...something like 8 or 10 sexual contacts a day, including everything from intercourse to oral sex. Common chimps are prevented from having quite this opportunity due to environmental factors (food scarcity), but they also engage in sex for gratification. There are a number of other species of course, but one that everyone's familiar with... Every time that neighbor's dog humps some one's leg, they're doing so for self gratification, not reproduction.
Last comment... the frequency of sex like this is largely influenced by environmental factors. Even in human societies, where survival is more difficult, people engage in less sexual activity generally.

Not every act of copulation in the animal kingdom results in childbirth.
