Creation & EvolutionForum for the discussion of this important topic. This forum is open to non-believers. There is a Christians-only forum in the Christians-only section too.
Not to mention sex is not confined to animals. Plants reproduce sexually and I'm confident plants don't feel pleasure. The first organisms to reproduce sexually did not have the capacity feel pleasure either.

But what distinguishes the worst architect from the best of bees is this, that the architect raises his structure in imagination before he erects it in reality.” — Karl Marx
“Imagination is not an empirical or superadded power of consciousness, it is the whole of consciousness as it realizes its freedom.” — Jean-Paul Sartre
Orgasms have a biological function - they are not there for pleasure only.
(Don´t ask me to describe the function of orgasms - I´m not a biologist, and would not be able to explain it properly)
Now pleasure is an organic reaction to something "good" (here in a biological sense): it makes the organism strive for such a stimulus.
"Good taste" makes you strive for a certain food - "bad taste" makes you want to avoid it.
And the pleasure from an orgasm makes you strive to reproduce - an evolutionary advantage.
The "desire" of orgasms can from the recognition that such a "pleasure" can be actively sought for.
So first came the orgasm - then the pleasure - then the desire.

How do you evolve desire? By reproductive success.
Take the desire to eat, fueled by an empty stomach. Those organisms that are not impelled to eat die of starvation. Same thing with sex, those that are not impelled to have sex do not pass down their genes to the next generation, and so the lineage of sexually apathetic individuals are bred out.
That, and desire is closely related to things under the control of gene expression, namely hormones. Desire is not a purely psychological emotion, but a psychosomatic drive that is written in our genes. For example, dairy farmers rely on in vitro fertilization. One of the steps in this procedure is causing the cow to ovulate. This is done by injecting hormones directly into the bloodstream. When this is done, it is very common for cows to mimic sexual acts on each other in the absence of a bull. Their desire is directly affected by the hormones in their body. Since DNA and genes are under the influence of evolutionary mechanisms (mutation and natural selection) and a desire to reproduce is obviously very advantageous, it is easy to conclude that desire for sexual copulation is something bred into us.
Next, let's look at the orgasm by using the analogy of addictive substances. Take cocaine, for example. Cocaine messes with your dopamine receptors, which causes a feeling of well being and euphoria, but in doing so the brain becomes reliant on this constant stimulation and craves the next 'hit'. The same brain activity and dopamine responses have been observed in sexual addicts. In fact, an orgasm releases these naturally made opiates into your blood stream, and the body can become addicted to this constant stimulation. Evolution locked onto a very simple idea, addict the body to orgasms through the use of chemical stimulation and in some cases addiction. In simpler organisms, such as corrals or barnacles, releasing sperm and eggs is a simple chemical cue, nothing that special. However, sexual selection and the loss of simple chemical cues required an added mechanism. And so we see the development of sexual "pleasure", with desire being controlled in a very similar fashion (hormones) as seen in simpler organisms.
It really isn't that hard to explain if you understand physiology and the influence that chemicals have on our emotions and desires.
You need food inorder to survive that is backed up by the fact that energy needs to be supplied in order to live. But, whats the need for sexual reproduction when organisms were reproducing asexually?
What's the need for a new food source when the old one still exists? Yet bacteria have evolved the ability to utilise all sorts of food sources, because it gives them an advantage over the ones that can't. Studies on sexual reproduction have shown that it also confers an advantage over asexual reproduction in some cases, particularly in terms of fighting the effects of parasites.

Concerning the expected circularity:
(One has said):I'd say the orgasm came before the desire for one
Then explain how orgasm came first, when every step of the progression toward it is contingent upon the anticipation of it.
Concerning the intellectual camp:
You tell us that we evolved orgasm in order to procreate. Sort of a matter of perceived efficiency.. survival.. self-preservation of the species. Eh....right.
So we evolved a pleasure that is higher than ourselves. Kind of like pulling yourself off the ground by your own bootstraps. I get it. Not.
And since when is pleasure the domain of the intellect? Since when is logic and preception the driver of physiological and emotional desire?
No. You all suffer from a self-enforced divorcement from reality: you examine life as though it were an economic equation.
Tell us, do you love your moms because it is necessary to support your parental heritage in order to keep society's fabric together, or do you just love her because she's your mom?
Time for you to stop playing android, and start to be human beings. Or life will pass you by in your silliness.
