Gender is indeed a complex concept, and it is true that having sex with members of the opposite sex has historically been considered an important part of gender guidance. At the same time, it is important to recognize that there is a wide range of gender identities and expressions which exist beyond the binary of male and female, and that people should have the freedom to express their gender in whatever way makes them most comfortable.
Additionally, it is important to recognize that gender has traditionally been defined in a certain way, and that it is not always easy for communities to adjust to such changes. Ultimately, we must strive to create a society that is inclusive and supportive of all gender identities, and that recognizes and respects the right of individuals to express their gender in whatever way makes them most comfortable.
