Long-term since, of problem of the sex on international familiar exist all the time with research an academic bottleneck, accordingly, extremely the quota system that is necessary to build and form a science, accurate to its assessment and hold, and cannot satisfy at blurring to be familiar with a level generally up to now. Solve this problem to need a brand-new scientific concept, this concept is sexual business.  

Who needs " sexual business " ? Famed safety covers England brand Du Lei this announced last year " global 2001 findings report " show, of the whole world married or cohabitational men and women is average one year sexual life frequency is 97 times. Among them the sexual life of American is the most frequent, a year average 124; It is Greek next, overcome Luo Deya's person, south Africa person, New Zealander and Italian, year average 110 for many times; Japanese is least, year have on average 36 times only. Person of Chinese Hong Kong, Taiwanese and the average number of inlander sexual life are 63 respectively, mix 65 times 72 times.

Professor Pan Suiming of institute of sociology of sex of Chinese people university once led 36 researcher, urban and rural to the whole nation the sexual life state of men and women of 64 years old undertook 3824 of 60 places 20 ～ understand. Findings is admirable: Married or cohabitational men and women is medium, the person that every month is less than even one-time life exceeded 1/4 (28.7%) ; What one-time life does not have is connect to be occupied unexpectedly in a the closest year 6.2% . Investigation still makes clear, the man can maintain the sexual life frequency that exceeds above every months average only 43.9 years old (losing difference 10.4 years old) . Arrived average 47.7 years old (losing difference 9.9 years old) , sexual frequency of the man under mensal; Arrived average 55.9 years old (losing difference 8.6 years old) , connect one year average sexual life was done not have, sexual life stops basically. And feminine sex life is briefer. The issue that the number shows makes us thoughtful.

Compare with the man woman photograph of world each district, sexual condition of the Chinese has to make a person anxious. Is this exaggerate sth just to scare people or fact after all? The research record of expert of each district medical treatment makes clear, the sexual function of compatriots shows downtrend really, the healthy level of this and compatriots and the occurence rate of all sorts of diseases are elevatory closely related. Because environment is exasperate, pressure of the job, life increases, life rhythm is accelerated wait for a reason, a few people just arrived middleaged begin to suffer from on senile disease, wait like heart disease, hypertensive, diabetic, prostatitis. In the meantime, the integral health condition of young crowd also nots allow hopeful. These reasons brought about the fall of sexual life level directly. However, the problem such as pressure of environment, life is global, a lot of countries are even more serious than China. As a result of the difference of humanitarian, environment of each district, racial diversity, structure of culture history, habits and customs, nutrition waits the objective existence of difference a moment, the comparison of the sexual level that makes us global to this kind makes rational assessment very hard. If have a pair of husband and wife healthy, did not maintain taller sexual life frequency, but relationship of husband and wife is good, sexual life is contented degree very tall also, by what do we say their sex level is low? Although evaluate them is sexual level low what sense to have again? Look, simple number can not show an issue the evaluation of integrated to the gender ability. Considering a lot of influencing factor, we have enough reason suspicion, the sexual level that with the number inside limits of this kind of whole world investigation measures a Chinese has break evenhanded. We are pressing the assessment technique of the sexual health level that needs a kind of can true positive and negative to mirror us.  

About the sexual health level of man, woman, include a few fields probably: Sexual physiology health, sex mental health and reproductive health. In Everyman in be familiar with, "Sexual level " be equal to " coital ability " , the directest measure dimension of frequency of sexual life of standard such as, duration, sexual organs to wait, its standard comes from A directly piece, advertisement of things of maize books and periodicals, sex. From the point of medical angle, put in a lot of errors, some are the misdirect of be blinded by gain simply. 2003 the beginning of the year, in " investigation of whole nation of quality of Chinese man life starts a press conference " on, standing director Wang He taught committee of major of doctor of traditional Chinese medicine of Chinese sex society to advance the idea of sexual business formally, to the sex that how measures a Chinese integrated level opened a door. With respect to the concept of sexual business, wang He points out, sexual business is due feature of its medicine physiology, but it is pure physiology index merely anything but, and should include sexual health psychology of ability of physiology of level, sex, sex is adjusted reach a gender the many respects such as interactive ability. With respect to the male character, it includes already " the gender longs to spend " , " erect function " , " abiding ability " , " sexual frequency " wait for oneself ability, also include to help a spouse achieve a gender cheerful or the ability of orgasm, when relevant problem is being encountered in also including to change in surroundings at the same time, use the capacity that certain intellectual measure and the healthy state of mind that keep certain have ego is adjusted. Can say, of sexual business concept put forward, make we saw the way that leads to a when measure condition of Chinese sex health correctly to bestrew light. In the meantime, about the controversy of sexual business, had not stopped since the day that this word is born.
