In this day and age, gender has now become personal preference and belief. I personally believe there are only to genders, but according to others there are more. First things first, many people seem to believe sex is what you were born as, or what your genitals are. There are only two sexes, male and female.
Gender, is what many people consider a "social construct". I personally don't believe this, but for the sake of the question let's say it is. Gender is what you believe you are, there are many genders such as agender, non binary, etc. etc.
According to most people, there is an infinite number of genders, but I guess it all comes down to what you believe.
I hope I helped!
