Abstract: At present, in the field of legislation on sexual crimes, there are a lot of controversy about whether sexual rights are protected equally regardless of gender, whether there is rape or not in marriage, and the victim's will violate the judgment standard in the academic circles, which needs to be further clarified in theory. Recently, Germany has promulgated the 50th Sexual Offences Amendment Act to strengthen the protection of citizens’ sexual rights. The main contents include: first, weakening the identification standards that violate the will of the victim, clarifying the principle of "no is no"; second, adding sexual crimes The "group responsibility" clause; third, adding the sexual harassment crime; fourth, clearing  "marital rape". The reform of German legislation on sexual crimes provides a useful reference for our country to realize equal protection of sexual rights, correctly handle marital rape, and optimize the identification standards of "violating the will of the victim".
