Since gender is a social construct, we can ourselves define how many genders there are. I think there are two, but some people think there are more. So my question is:

  • is the number of genders specific? If so, how many are there and where's the list of them?

  • is the number infinite? Can I declare myself as 85% man and 15% woman, or any other combination?

  • can I change my gender after some time, or is it fixed once I declare it? If I declare myself a woman tomorrow, will I be subjected to sexism and should I be able to use women's facilities?
