Clinically, a very troubling disease for men is premature ejaculation, which not only hurts a man’s self-esteem, but also wreaks havoc on family happiness. But in fact, about 70% of people are pseudo premature ejaculation, the common reasons are as follows: 1, can not cause female sexual pleasure Male and female functions play a male fast female slow characteristics, male performance for erection quickly, soon into the orgasm and ejaculation; female sexual excitement appears slower, usually after ten minutes, or even longer some time to come slowly. This is a natural difference, so male ejaculation occurs while the woman has not yet reached orgasm is commonplace. This situation is at most a sexual intercourse with the disharmony, and can not be considered a problem for the male. 2, newlywed premature ejaculation The newlywed stage is prone to premature ejaculation, one is the newlywed stage of sexual excitement is particularly high, full of longing and desire for sex, both fresh and curious, easy to stimulate ejaculation. The second is just beginning sex, the couple has not yet reached the realm of satisfactory cooperation, the play of sexual function has not fully entered the normal state, prone to premature ejaculation. 3, after a long time without sexual intercourse rapid ejaculation between the couple did not meet for a long time, rapid ejaculation occurred during sex think they suffer from premature ejaculation, worry about their sexual function has a problem. In fact, there is an inverse relationship between the quickness and slowness of the ejaculation time and the length of time between intercourse. In other words, frequent sexual life, short interval between each sexual life, ejaculation appears more slowly. On the contrary, the sexual life is not much, in a long time no sex life “sexual hunger” condition, sexual excitement suddenly increased, once the sexual intercourse will be faster ejaculation. 4, erectile dysfunction Premature ejaculation and erectile dysfunction have different pathogenesis and are not causally related to each other. However, some patients, after a longer period of premature ejaculation, have erectile dysfunction, which is the result of psychological factors. 5, faster than others ejaculation ejaculation fast or slow does not need to be compared with others at all, because everyone’s sexual physiological activities are different, and sexual life experience and frequency of sexual life are not exactly the same, so there is no comparability.
