Q: What does sex queer mean

Answer:
Answer: Sex queer is a kind of gender identity, or experience or expression of gender. Different from the mainstream gender dualism, gender queer may feel that her gender is between male and female, that she is neither male nor female, or that she is both male and female, or that she completely rejects any "gender". In the West, the gender queer is closely related to the theory and practice of "cross gender" and "queer". The queer theory proposes that the homosexual movement should go beyond the solidified identity and challenge social norms. The cross gender movement further criticizes the binary gender system that divides men and women. In the non western culture and history, there are also various cultures that challenge the dual gender concept of men and women, such as Hejira in Indian culture, "Shuangling" in North American aboriginal culture, and "X gender" in Japan.
