With the formal establishment of sexology in 1885, from the beginning of 20th century to the end of 1930s, sexology also established its status as a branch subject with a series of achievements. At that time, the main sexual sociologists and their research results were as follows: I. Bloch, a German scholar, was the first master to study social neutrality. His main works are: Sexual Life in Our Times and Its Relationship with Modern Civilization (1907), Social Roots of Syphilis, Prostitutes (2 volumes) and On Morality? Sade, British sexual life, psychological research on sexual system diseases, anthropological research on strange sexual behavior, etc. In the United States, the pioneer G.V. Hamilton asked 80,000 married men and women 400 questions about sexual life, and published the information book "Marriage Survey". Another pioneer, gynecologist K.B. Davis, was the first to investigate the social aspects of women's sexual behavior, and published 2200 women's sexual factors in 1929, so she was regarded as a pioneer of women's sexology. During this period, the most important achievements of sexual sociology were put forward, disseminated and recognized; There is a close relationship between social and sexual phenomena.

From the late 1930s to the early 1950s, it was the period when sociology of sex founded its own basic theory. The most famous figure at that time was Lake in Germany. He studied the relationship between sexual phenomena and social power and founded sexual politics. His main works are: 1932 "Sexual Rights and Sexual Morality Oppression of Youth", 1933 "Popular Psychology of Fascism" and 1936 "Sexual Revolution: Personality Structure Towards Self-management". Another famous scholar is American A.C. Kinsey. After a large number of social surveys, he published the Kinsey Report: Human Male Sexual Behavior (1947) and Human Female Sexual Behavior (1953). He analyzed the process of people's socialization and the important role of people's different social stratum environment on people's sexual behavior and orgasm frequency.

Of course, some scholars later thought that the real object of Lake's research was not sexual phenomenon, but social and political phenomenon. In fact, Jin initiated the social investigation school of sexology, not the study of sexual phenomena in sociology; So the sociology of sex itself actually stagnated during this period. Since the early 1950s, it has been a period of development of sociology of sex. This is mainly manifested in three aspects.

① Social investigation reports about sexual phenomena are constantly emerging, which generally aroused great social repercussions. The more important achievements are: Hunt's Sexual Behavior in the 1970s (1976), Hite's Summary of Sexual Investigation in Red Book Magazine (also translated into Hite's report on sexuality) and E. Lauman's Social Organization of Sexual Phenomenon (1995). However, due to the different academic backgrounds of researchers, a considerable part of many surveys do not conform to the general norms of social surveys, which greatly reduces their academic significance.

(2) The macro and speculative research on the relationship between sexual phenomena and society has been developing continuously, which has played a great role in human understanding and thinking about sexual phenomena. For example, Marcuse's Love and Civilization, Foucault's History of Sex and so on. However, some scholars believe that the achievements in this field generally tend to philosophy, and it is best not to classify them as sociology of sex.

③ Establish a relatively recognized and standardized theory of sexual sociology. From 65438 to 0973, the book Sexual Behavior-Sexual Social Organization, co-authored by J Gagnion and Simon, systematically discussed the socialization process and its laws of human sexual behavior for the first time, pointing out that the so-called sexual development is not only a process of physical growth, but also a process of personal identification and domestication in the sexual culture of the society in which he lives, and the latter is often more important. It is generally believed that this is the birth of the theory of sexual sociology itself. In 1980s, Moni published a series of works to study how the previous concepts and research processes of sexuality were restricted and influenced by social culture. His masterpieces are men and women, boys and girls. It is generally believed that this marks the beginning of classical sexology, which is dominated by psychology and physiology, towards inclusive sociology and comprehensive disciplines. From 65438 to 0995, Lauman, Gagnion and others published the book "Social Organization of Sexual Phenomenon" (commonly known as "Chicago Report"), systematically established the social network theory of sexual phenomenon, and analyzed the data of the first random interview survey in American history. Verified his theory. Their theoretical basis is that, unlike the classical sexology in the past, they no longer regard sexual phenomena as the product of individualization, but demonstrate that human sexual phenomena actually occur and exist in the relationships and interactions between people, and the relationships and interactions among many people form the network of sexual phenomena in the whole society. This is a social organization in sex, and its structure, function and mechanism play a more important role in individual phenomena than classical sexology and the past. Although it will take a long time to test this research result, it is generally believed that it may mark the maturity of the theory and application of sexual sociology and the firm establishment of this relatively independent branch discipline.
