Many men have this experience, the night of the wedding, due to the lack of knowledge between the couple, the first sex when ejaculation faster, after living together for a period of time, ejaculation will be slower. There are also some separated couples who have not had sex for a long time and suddenly meet, ejaculate faster than normal, and live together for a while and get better. Can this phenomenon be considered premature ejaculation? Generally speaking, it is not considered to be premature ejaculation, but a normal phenomenon. (1) The problem of sexual excitement is too high: because of the premarital stage of love and intimacy, both the brain layer of sexual activity “command”, or sexual organs, are often in a high state of sexual excitement, which inevitably causes the ejaculation center is also in sexual excitement, the requirements for sexual stimulation is reduced, that is, to reduce the “threshold” of sexual stimulation. At the same time, for a newlywed man, the first time to contact the woman in the form of sexual life, this sexual stimulation is both sudden and very strong, it is not surprising that ejaculation occurs more quickly. (2) is the stimulation of semen accumulation: unmarried men due to the production of semen in the reproductive organs to reach a certain amount, to be discharged in the form of seminal emission. The first time a newlywed man, before sexual intercourse, the sexual organs have accumulated a considerable amount of semen, can produce a satiety-shaped stimulation, coinciding with sex, will be eager to discharge prematurely. (3) is the reason why the sexual function has not yet normal play: here refers to the sexual function is not a problem, but refers to the sexual function meets the turning point of this form of sexual life, the initial stage may not be fully adapted, nerve, endocrine activities of the various links, not all straightened out, the beginning stage will appear premature ejaculation phenomenon, and later gradually adapt and get used to, will return to the normal. Know the reasoning behind this, once the newlywed stage of ejaculation faster, there is no need to worry about this, otherwise mistaken for sexual function problems, resulting in psychological and mental damage, will really induce sexual dysfunction.
