Premature ejaculation (PE), also known as rapid ejaculation, premature climax, early ejaculation, or by the Latin term ejaculatio praecox, is the most common sexual problem in men, affecting 25%-40% of men. It is characterized by a lack of voluntary control over ejaculation. Masters and Johnson stated that a man suffers from premature ejaculation if he ejaculates before his partner achieves orgasm in more than fifty percent of his sexual encounters. Other sex researchers have defined premature ejaculation as occurring if the man ejaculates within two minutes or less of penetration; however, a survey by Alfred Kinsey in the 1950s demonstrated that three quarters of men ejaculated within two minutes of penetration in over half of their sexual encounters. Today, most sex therapists understand premature ejaculation as occurring when a lack of ejaculatory control interferes with sexual or emotional well-being in one or both partners. Masters and Johnson recommended the use of the lateral coital position to help alleviate premature ejaculation.

Most men experience premature ejaculation at least once in their lives. Often adolescents and young men experience "premature" ejaculation during their first sexual encounters, but eventually learn ejaculatory control. Because there is great variability in both how long it takes men to ejaculate and how long both partners want sex to last, researchers have begun to form a quantitative definition of premature ejaculation. Current evidence supports an average intravaginal ejaculation latency time (IELT) of six and a half minutes in 18-30 year olds.[1] If the disorder is defined as an IELT percentile below 2.5, then premature ejaculation could be suggested by an IELT of less than about one and a half minutes. Nevertheless, it is well accepted that men with IELTs below 1.5 minutes could be "happy" with their performance and do not report a lack of control and therefore do not suffer from PE. On the other hand, a man with 2 minutes IELT could present with perception of poor control over his ejaculation, distressed about his condition, has interpersonal difficulties and therefore be diagnosed with PE.

Scientists have long suspected a genetic link to certain forms of premature ejaculation. In one study, ninety-one percent of men who suffered from lifelong premature ejaculation also had a first-relative with lifelong premature ejaculation. Other researchers have noted that men who suffer from premature ejaculation have a faster neurological response in the pelvic muscles. Simple exercises commonly suggested by sex therapists can significantly improve ejaculatory control for men with premature ejaculation caused by neurological factors. Often, these men may benefit from anti-anxiety medication or selective serotonin reuptake inhibitors (SSRIs), such as sertraline or paroxetine. Some men prefer using anesthetic creams; however, these creams may also deaden sensations in the man's partner, and are not generally recommended by sex therapists.

Psychological factors also commonly contribute to premature ejaculation. While men sometimes underestimate the relationship between sexual performance and emotional well-being, premature ejaculation can be caused by temporary depression, stress over financial matters, unrealistic expectations about performance, a history of sexual repression, or an overall lack of confidence. Interpersonal dynamics strongly contribute to sexual function, and premature ejaculation can be caused by a lack of communication between partners, hurt feelings, or unresolved conflicts that interfere with the ability to achieve emotional intimacy. Neurological premature ejaculation can also lead to other forms of sexual dysfunction, or intensify the existing problem, by creating performance anxiety. In a less pathological context, premature ejaculation could also be simply caused by extreme arousal.

Some physical illnesses, such as a prostate infection, are also known to induce premature ejaculation. In other instances, premature ejaculation is caused by a physical injury that affects the nervous system. Certain medications, such as cold medications containing pseudoephedrine, also cause premature ejaculation. Sexual dysfunction is a common symptom of psychiatric afflictions ranging from bipolar disorder to post-traumatic stress disorder. In these cases, it is best to discuss the issues openly with a physician.

Today it is believed that the neurotransmitor serotonin (5HT) has a central role in modulating ejaculation. Several animal studies have demostrated its inhibitory effect on ejaculation modulated through the PGI system in the brain. Therefore, it is perceived that low level of serotonin in the synaptic cleft in these specific areas in the brain could cause premature ejaculation. This theory is further supported by the proven effectiveness of SSRIs, which increase serotonin level in the synapse, in treating PE.

Treatment

Depending on severity, premature ejaculation symptoms can be significantly reduced. In mundane cases, treatments are focused on gradually training and improving mental habituation to sex and physical development of stimulation control. In clinical cases, various medications are being trialled to help slow down the speed of the arousal response.

SSRI antidepressants have been shown to delay ejaculation in men treated for different psychiatry disorders. SSRIs are considered the most effective treatment currently available for PE. These include paroxetine, fluoxetine, sertraline and more. The use of these drugs, that require chronic therapy is limited by the neuropsychiatric side effects. New SSRI drugs specifically targeted to treat premature ejaculation (e.g. dapoxetine) can be taken on an as needed basis and have been recently shown positive results in large phase III studies. Nevertheless dapoxetine is not yet approved by any regulatory authority around the world. There is speculation that some of the associated effects are caused by lowered libido and blood pressure as well as lowered anxiety levels. Other pharmaceutical products known to delay male orgasm are; opioids, cocaine, and diphenhydramine.

Local anesthetic creams (like lidocaine, prilocaine and combinations) have shown to be very effective in clinical trials and are being used of the treatment of PE. Their use is limited by its own anesthetic effect that reduce sensation on the penis and vagina.

Most sex therapists prescribe a series of exercises to enable the man to gain ejaculatory control. While the exercises are intended for men who suffer from premature ejaculation, other men can use the exercises to enhance their sex lives. By far the most common exercise is the so-called start-stop technique. While the technique varies, the purpose is to get the male accustomed to maintaining an erection for an extended period of time while gradually increasing sexual tolerance. In doing this exercise, the male obtains an erection through self-stimulation, or masturbation. After achieving an erection, he stops stimulating himself until he begins to lose his erection; at that point, he begins to stimulate himself again. Gradually, over a period of several weeks, he is able to stimulate himself for longer periods of time, eventually gaining ejaculatory control. In order for this technique to be successful, the male should avoid feeling discouraged if he ejaculates rapidly; instead, he should use his sexual responses to learn how to vary the technique in a way that most benefits him. Another variant, for example, is to stimulate the shaft and frenulum of the penis, exploring the glans more as control improves.

Diagnosis

Diagnostic criteria for Premature Ejaculation from the DSM-IV (American Psychiatric Association)

1. Persistent or recurrent ejaculation with minimal sexual stimulation before, on, or shortly after penetration and before the person wishes it. The clinician must take into account factors that affect duration of the excitement phase, such as age, novelty of the sexual partner or situation, and recent frequency of sexual activity.
2. The disturbance causes marked distress or interpersonal difficulty.
3. The premature ejaculation is not due exclusively to the direct effects of a substance (e.g., withdrawal from opioids).

I was researching how to fix my problem when we have sex. I think it is something that we should both read and try the things they suggest so I could better serve you and I. Love you
