For the purpose of special protection for “vulnerable groups”, the phenomenon of “gender assumption” exists in the criminal law of our country, and the legislative setting of rape crime is the most prominent example. With the development of theoretical research and judicial practice, the neglect of the rights and interests of non-female groups in rape crime not only makes some crimes of similar nature not properly regulated and the purpose of criminal law protection law not really realized, but also causes researchers to question whether the provisions of rape crime formulated based on “gender” are protection or discrimination. Judging from the current judicial practice, there are some problems in Chinese provisions on rape crime, such as the absence of the subject and object of the crime, the dispute over the protection law interests, the lack of clear qualitative definition of new sexual behavior, the need to expand compulsory means, the urgent need to improve legal punishment, and the need to innovate judicial handling methods. Standing on the shoulders of giants can get a broader vision, by summarizing the previous research results to accumulate knowledge, inspire inspiration and find problems, it is a reasonable and efficient method.
