Men in sex is the last word in a lasting 男人在性爱中持久才是硬道理

For men, time, hard in pursuit of sex, not just to prove their personal abilities, but also to take care of the needs of a partner. A recent British survey found that the substantive cross long enough time, is to ensure women's access to the climax of the necessary elements.

According to the British "The Times" reported that the Department of Psychology, Professor Stuart West of Scotland University of Tebuluodi found that more than 50% of women need at least 10 minutes of the substantive pay is only possible to reach orgasm; if men can stick to 15 minutes, that this proportion will increase to 2 / 3. "Further analysis also shows that even the female clitoris orgasm, but also the need for adequate duration of vaginal stimulation."

Tsinghua University Yuquan Hospital of Medicine J. Yang, complete sex consists of three parts, the first opera, the substantive pay and post-drama, in which the proportion of heavier proportion of substantive pay in order to provoke each other's desire to harvest high-quality sex. In 2008, the United States Institute of Pennsylvania more than a Rand study confirms, the substantive pay of the ideals of length 7-13 minutes. Eric is responsible for the study? Coulter introduction, the United States and Australia have thousands of people participated in the study, most respondents, especially men, said the substantive pay of less than seven minutes, there will be boundless feeling.

However, for some couples, even if it is 7 minutes, is an elusive goal. One for the general ED (erectile dysfunction), and diseases associated with the basic survey of ED patients, ED patients with erectile duration is far shorter than the normal group. Among them, patients with untreated ED erectile duration of about 0.6 minutes, with basic illness such as diabetes, abnormal blood lipids, erection duration is only 0.43 minutes. So for these ED patients, "Enduring is the last word"!

Vice president of China Institute of Tsinghua University Yuquan Hospital Medicine Professor Akitoshi Coma, by definition, ED sub-two meanings, the first layer is not get an erection, such as husband and wife together, the husband is not totally excited up, the penis that can not harden; standing, with little or no upturned angle. The second layer is unable to maintain an erection, in this case, men can be excited, the penis can also be lifted, but the real soft when inserted, or inserted yet how activity continue not to go on. In 2001, an ED treatment for men online survey also shows that, when asked "what are the factors for ED treatment of important or very important", select the duration and hardness of erection who have reached 93%. Thus, for male ED patients, the duration and hardness of erection as important as "hard is not enough light, but also to hard too long."

Recently, the world's first study of ED erection duration is found that taking PDE5 inhibitors - vardenafil (trade name Levitra), it can significantly extend the duration of an erection, an increase of 2.5 to 3 times, fully meet the ideal sexual intercourse length; even if accompanied by lipid abnormalities in patients with ED taking Levitra, the extended duration of erection can be achieved 3 times. In this study, based on some experts have proposed, ED treatment should be comprehensive consideration of patients with deep-seated needs, that is, to obtain satisfaction of sexual relations between partners, which include improving erection hardness of erection and prolong the duration of these two important factors, ED treatment in order to achieve the real purpose: to restore a satisfactory sexual relationship.


男性对于性爱时间的苦苦追求，并非只是为了证明个人能力，更是为了照顾伴侣的需求。英国一项最新调查发现，足够长的实质性交时间，是保证女性获得高潮的必要因素。

据英国《泰晤士报》报道，西苏格兰大学心理学系教授斯图亚特布罗迪发现，超过50%的女性需要至少十分钟的实质性交，才可能达到高潮；如果男性能坚持到15分钟，那这一比例将上升至2/3。“进一步的分析还证明，即使是阴蒂高潮的女性，也需要足够时长的阴道刺激。”

清华大学玉泉医院性医学科杨大中指出，完整的性爱包括三部分，前戏、实质性交和后戏，其中实质性交占比较重的比例，以激起彼此的欲望，收获高质量的性爱。2008年，美国宾夕法尼亚州比兰德学院的一项研究证实，实质性交的理想时长为7—13分钟。负责该项研究的埃里克?寇特介绍，美国和澳大利亚有上千人参与了该项研究，多数被调查者，尤其是男性表示，实质性交少于7分钟，会有意犹未尽之感。

然而，对一部分夫妻而言，即使是7分钟，都是一个可望而不可及的目标。一项针对普通ED（勃起功能障碍）及伴有基础性疾病的ED患者进行的调查显示，ED患者的勃起持续时间远远短于正常人群。其中，未经治疗的ED患者勃起持续时间约为0.6分钟，而伴随基础性疾病者，如糖尿病、血脂异常等，勃起持续时间仅为0.43分钟。因此对于这些ED患者来说，“持久才是硬道理”！

中国性学会副理事长、清华大学玉泉医院性医学科马晓年教授介绍，从定义上看，ED分两层意思，第一层是不能获得勃起，比如夫妻两人在一起，丈夫完全兴奋不起来，阴茎一点都不能变硬；站立时，几乎甚至完全没有上翘的角度。第二层是不能维持勃起，在这种情况下，男性能兴奋起来，阴茎也能抬起，但真正插入时就软了，或者插入后还没怎么活动就继续不下去了。2001年，一项针对男性ED治疗效果的在线调查也表明，当被问及“何种因素对于ED治疗重要或非常重要”时，选择勃起持续时间和硬度者都达到了93%。由此可见，对于男性ED患者，勃起持续时间和硬度同等重要，“光硬还不够，更要硬得久”。

近日，全球首个研究ED勃起持续时间的试验发现，服用PDE5抑制剂——伐地那非（商品名艾力达）后，可以显著延长勃起持续时间，提高2.5到 3倍，完全满足理想的性交时长；即使伴有血脂异常的ED患者，服用艾力达后，延长勃起持续时间能够达到3倍。在这一研究基础上，有专家提出，ED治疗应综合考虑患者的深层次需求，那就是获得伴侣间性关系的满意，这其中包括了改善勃起硬度与延长勃起持续时间这两个重要因素，这样才能达到ED治疗的真正目的：恢复满意的性关系。
