① Gender differences refer to the differences between men and women in physiology, anatomy and heredity, such as sex chromosomes, gonads, sex organs, sex hormones and secondary sexual characteristics.
② Gender difference refers to the psychological difference between men and women, which is mainly manifested in personality, feeling, temperament, intelligence and emotion.
③ Gender role difference refers to the difference of social behavior patterns between men and women, such as the role division of family and professional posts. However, the natural differences between men and women mentioned above will never affect the equal rights of men and women in education, politics, employment and personality. Of course, it will not hinder men and women from enjoying the right of independent love and being loved in sexual life.
