Since you are not as intelligent as Oxford, I will have them explain what gender is:

“ Either of the two sexes (male and female), especially when considered with reference to social and cultural differences rather than biological ones. The term is also used more broadly to denote a range of identities that do not correspond to established ideas of male and female.”

Nobody cares about your feeling Chloe. Gender refers to non-biological traits. This is science. This is psychology.

If you cannot handle that, then go back under your rock.
