When this question is thought in a more universal (and perhaps idealistic) context, my answer is simple: you are responsible for only yourself. Who you are should be only representative of you, but in the context of gender and society, the answer is more complex. We are categorized by society, whether it be as male, female, or other or straight, gay, or anything in between. Everyone has a stereotype, and if you do not think you do, you are the stereotypical outsider. It is your responsibility, therefore, to either conform to your stereotype or fight to break it. But even if you break it, you still had to accept and address your stereotype initially. This responsibility may not be intentional or even conscious. But every time, for example, a woman wears a dress to impress a guy, she is taking the responsibility of perpetuating her stereotype.
