"Apart from objects, another basic form of identification is with “my” body. Firstly, the body is male or female, and so the sense of being a man or woman takes up a significant part of most people's sense of self. Gender becomes identity. Identification with gender is encouraged at an early age, and it forces you into a role, into conditioned patterns of behavior that affect all aspects of your life, not just sexuality."
