MakymastercomsYou may be confusing sex and gender if you think there are only two genders. Gender is your traits that come from masculinity/femininity and hence it is on a spectrum. Sex is the entirely biological aspect and is what you would consider traditionally to have two states: male and female.

Sex and gender are synonymous, you cannot divide a category of biology into two separate categories. I am not denying the idea of other genders/sexes but as of now there are two; Male and Female. Now if you want to get technical we can talk about hermaphrodites and transvestites but at the end of the day they choose a single gender/sex and they make up a minuscule number of society. You can identify as whatever you want, you deserve to be happy, and I will respect your choice.
thats the language definition not the scientific definition you mong
