Premature ejaculation was once thought to be caused by drugs or certain infections such as urethritis, but popular wisdom suggests it is more psychological in nature. The exact cause of the condition, however, still remains a mystery. Premature ejaculation often occurs during the first experiences with sex, and in this case is most commonly attributed to anxiety. The majority of men gradually learn to control their orgasm, and have no lasting effect. Some men will develop a longer-term anxiety toward sex, which can cause a prolonged experience with premature ejaculation.
Sexual behavior is also a factor.
The longer the period since last ejaculating, the quicker young men typically reach orgasm. Younger men tend to ejaculate more quickly than older men, as experience seems to be associated with ejaculatory control. Not everyone who has lost the raging passion of youth has impaired circulation. By the same token, not every healthy male or female with sexual dysfunction has a psychiatric disorder. In fact, most of us are normal but just overwhelmed with the stress of life.
