EPremature ejaculation
What is premature ejaculation? But before we go to that part let see first what is ejaculation
Let see what is ejaculation as explain by Saffron Whitehead in answers.com
"Ejaculation of semen is the final outcome of a complex series of reflexes induced by sexual arousal and stimulation. The reflexes involve both the sympathetic and the parasympathetic branches of the autonomic nervous system, as well as spinal motor nerves and descending nerves from the brain. Three phases of the ejaculatory response can be defined — erection, emission, and ejaculation itself.
Erection is caused by changes in blood flow to the penis that can be induced by tactile stimulation of the genital region, particularly the glans penis, which has a high density of tactile-pressure receptors. This sensory information is relayed by sensory nerves to the lower spinal cord which, via parasympathetic nerves, causes dilation of arterioles in the penis. As a result blood inflow to the spongy sinuses increases dramatically and they become engorged. Because these erectile regions are surrounded by a strong fibrous coat, the penis becomes enlarged and rigid. Also, as the erectile tissue expands the venous outflow from the penis is compressed, so while inflow of blood increases, through flow does not, and erection results. Simultaneously, parasympathetic nerves stimulate the bulbo-urethral glands to produce a mucoid substance to aid lubrication. Erection can also occur in the absence of any tactile stimulation, when thoughts, visual cues, or emotions stimulate descending nerve pathways from the brain. These, in turn, activate the same nerves as those reflexly stimulated by sensory stimulation of the genital region.
During the second phase of the response (emission), contractions of the smooth muscle in the walls of the vasa deferentia, and the ejaculatory duct formed by their junction, push sperm into the upper part of the urethra. At the same time the seminal vesicles and prostate gland contract and release seminal fluid into the urethra. (See urogenital system)
In the third phase, ejaculation proper, which occurs at orgasm, the semen (sperm plus seminal fluid) is expelled from the posterior urethra by contractions of the muscles which surround it. During coitus ejaculation is also associated with involuntary rhythmic thrusting of the pelvis. The role of the sympathetic branch of the autonomic nervous system at this point is to contract the sphincter round the neck of the bladder, so that ejaculation cannot backfire in that direction.
A feeling of intense pleasure usually accompanies ejaculation, and the whole event is known as orgasm. After this there is the resolution phase in which all the physiological changes which have occurred are reversed and a man becomes refractory to any further sexual stimulation for a while. This period can last from a few minutes to several hours.
Any interference with the relevant spinal reflexes can cause impotence and other sexual dysfunction, although libido will be unaffected. The central nervous system plays an important role in regulating the sexual response, not only in normal individuals but also in cases of disordered sexual function. Whilst sexual arousal can be stimulated or enhanced by visual or other inputs of a sexual nature in the absence of tactile genital stimulation, conversely the sexual response may be suppressed by the central nervous system, either consciously or subconsciously. This can lead to impotence, loss of sexual interest, premature ejaculation, ejaculatory failure, or a loss of the usual generalized accompaniments of orgasm. These are all common defects of this complex reflex response and may have a psychogenic basis in some patients. They are often amenable to behavioural therapy.

What is it?
Premature ejaculation is one of the most common sexual problems.Premature ejaculation (PE) means coming too quickly, and it's one of the most common sexual problems.In our survey of several thousand British males, approximately 10 per cent of them said that they often or sometimes had this trouble.We found that it's commoner in younger men – which is not surprising, as there's a distinct tendency for it to improve with age. Men generally get better control as they grow older.
However, a 2004 survey in Europe showed that many middle-aged men still have this problem. Fortunately, good treatments are available.In 2010/11, a new treatment became available in Britain and several other countries – details below.
Definitions
It’s almost impossible to get an accurate definition of premature ejaculation: what some couples consider a satisfactory length of intercourse would be very inadequate for others.At the 2006 Congress of the European Society for Sexual Medicine, an American research paper reported:the average lasting time of men with PE was 1.8 minutes'normal' men lasted an average of 7.3 minutes.But there were males who claimed to have premature ejaculation, yet who could last up to 25 minutes. This clearly shows people have wildly differing ideas about what is normal!
At the same Congress, Professor Waldinger reported that 2.5 per cent of men couldn't last 90 seconds inside the vagina. Those males undoubtedly have PE.
From our own clinical experience, there are plenty of couples who would regard intercourse that lasts under 20 minutes as less than satisfactory, and would feel that any ejaculation in under 10 minutes or so is decidedly premature.As a working definition, if either you or your partner feels that orgasm is happening too soon, there probably is some degree of PE.

Premature Ejaculation
Definition
Premature ejaculation occurs when male sexual climax (orgasm) occurs before a man wishes it or too quickly during intercourse to satisfy his partner.
Description
Premature ejaculation is the most commonly reported sexual complaint of men and couples. The highest number of complaints is among teenage, young adult, and sexually inexperienced males. Increased risk is associated with sexual inexperience and lack of knowledge of normal male sexual responses.
Causes and symptoms
There are several reasons why a man may ejaculate prematurely. For some men, the cause is due to an innate reflex or psychological predisposition of the nervous system. Sometimes it can be caused by certain drugs, such as non-prescription cold medications. Psychological factors, such as stress, fear, or guilt can also play a role. Examples of psychological factors include guilt that the sexual activity is wrong or sinful, fear of getting caught, or stress from problems at work or home.
In general, symptoms are when a male reaches climax in less than two minutes or when it occurs before the male or couple want it to occur.
Mayoclinic Definition:
Premature ejaculation occurs when a man ejaculates sooner during sexual intercourse than they or their partner would like. As long as it happens infrequently, it's not cause for concern. However, if you regularly ejaculate sooner than you and your partner wish — such as before intercourse begins or shortly afterward it can be considered premature ejaculation.According to the International Society for Sexual Medicine, lifelong premature ejaculation is characterized by:
Ejaculation that always or nearly always occurs within one minute of vaginal penetrationThe inability to delay ejaculation on all or nearly all vaginal penetrationsNegative personal consequences, such as stress, frustration or the avoidance of sexual intimacy
Secondary premature ejaculation is generally understood to share the same symptoms as lifelong premature ejaculation, but with one key difference:Secondary ejaculation develops after you've had previous, satisfying sexual relationships without ejaculatory problems.
