男人快感的秘密
  睪酮是主要的男性荷爾蒙,這種荷爾蒙促使生殖器官發育,產生勃起和性行為,第二性徵,如聲音變粗,鬍鬚生長等也是這種荷爾蒙 的作用。睪丸分泌大量的睪酮。位於腎上方的腎上腺,無論男女都會分泌極少量的睪酮。腦的視丘下部控制著荷爾蒙的分泌,當睪酮水平 下降時,視丘下部就會向腦底部的垂體發出信號,腦垂體就會通過血流送出荷爾蒙使者,告訴睪丸加速分泌。男性的荷爾蒙水平範圍變化 很大,但大多數男性的睪酮流通量比他們的需要量要多。一個睪酮水平低的男性,可能在勃起和保持勃起狀態時碰到困難,並失去性慾。 在健康的男性中,荷爾蒙問題極少見,常見的是因焦慮引起的不能勃起問題。不能勃起問題的醫學原因包括在骨盆的血管與神經的問題。 當大腦沿著脊髓傳送一個勃起信號並經過了穿過骨盆的神經時,勃起就會發生。前列腺外面佈滿一些重要的神經。當勃起的信號通過神經 系統時,陰莖內的海綿組織會鬆弛下來,將血液送進陰莖的動脈血管則會擴張,隨著血管壁的伸展,血液以高於平時五十倍的速度流進來 ,充滿兩側的海綿體,陰莖內的平常負責排出血液的血管,現在卻減慢這一過程,陰莖內的血壓急升,堅挺的勃起現象出現。當陰莖在摩 擦時,使得控制血流的神經被刺激,這時候男人就會有快感。即便是因為神經或血管堵塞等問題而無法勃起,男人還是會從摩擦中體會到 快感並到達高潮。
  第三神經控制男性射精,射精是高潮的第二步。一個男性的高潮有兩步。第一步是發射,前列腺,精囊,輸精管協作,使得睪丸產生 的精子細胞和精液混合,精液是由前列腺和精囊產生的一種白色並富含蛋白質的液體,使精子細胞能夠存活。這一混合物存於尿道頂部, 等待發射。當已非射不可時,男性會感覺到高潮即將來臨。高潮由交感神經所控制。第二步是射精,控制射精的神經與男性外陰被撫摸產 生快感信號的神經相同,這些神經引起陰莖根部肌肉有節律擠縮,將精液通過尿道射出,同時,快感信息傳至大腦,快感隨之產生。

Gender life prime time


In the time of day and night, the sex what is better? A lot of couples are very concerned about this problem, sexologist also continue exploration and study it. Sex life time arrangements should normally consider two questions; First, not fatigue the situation under sex two sex life after a sufficient rest and recovery time of physical. From the practical point of view of the present life, to the following three statements.

One, it was felt that the night time as well. The so-called night, generally refers to about 22:00, a considerable number of people, which is about to fall asleep. Who hold this view believe that sexual activity need to pay a larger physical sex during this time, after it's happened can immediately go to sleep, so that they get enough rest, the next day can keep plenty of energy;

Two, it was that morning, around 6:00 as well. The people hold the views that have been restored after a night of rest, physical, sexual life, a better energy. From a physiological point of view, the concentration of adrenal hormones in the human body, sexual desire is also the strongest at this time. Sex during this time, you can enter a short period of time the state of sexual excitement. After sexual intercourse, not timely rest, and immediately engaged in work, study, but because of the one-time life-consuming physical is not large. Early morning sex, sex life, without fatigue, discomfort to determine whether suitable. (Reminder: The sex life should not be in the morning)

Third, some argue, the best sleep for a few hours, wake up sex for good. People think that holding such a view of the rapid pace of modern life, 8 hours a day of learning, work, most of the more fatigue, the evening would also like to enjoy the relaxed nightlife, want to make the necessary social interaction, generally at night to sleep late, in this case the sexual life, to bodily weakness, the spirit of slack, not necessarily mutually satisfactory. Sleep to get the necessary rest for some time that physical and mental energy have been restored, after sexual intercourse can also sleep for several hours.

The above three statements each have their own point of view, each have their own reason. Hard to say what kind of absolute advantage or disadvantage, however, a considerable part of the couple's habit, the first argument the most common. In fact, the choice of timing of sexual life, the initiative in every couple of hands, what time of sex, should be based on the arrangement of the two sides to work, study, physical energy, mood status, and sexual habits of life, preferred to decide. Such as sexual function in people with weakened selection in the morning will be conducive to compensate for their weaknesses; work effort is easier to maintain strong effort at bedtime.

In short, the time of the sexual life is not as obvious as long as both spouses recognize and like, do not affect each other the next day's work to learn to choose what time is appropriate, do not invariably insist.
