How many genders are there ?

The term, "sex" refers to the biological differences between a male and female, such as the genitalia and genetic differences.
The "Gender"is more difficult to define, but it can refer to the role of a male or female in society, known as a gender role, or an individual's concept of themselves, or gender identity.

Sooo.. I gues we only have 2 sex (sounds weird, thats why everyone uses gender and not sex) but maybe everyone just thinks that you also can only think of yourself as a male or female ^^

Though I have seen some definition there is still some people who are unaware of the difference between biological sex and gender. Sex is the physical attributes that differentiate you between the other gender while gender is what someone would identify as.

There is not limit for that, the simplest answer will be infinite, but sex type just 3. Male, female and intersexual(hermaphrodite)

it's a spectrum - not a number. just like you can be a bit gay or fully hard-on gay.

theres 3 , trans male and female, no need to cut out the trans just because they are differen

I would say unlimited, and the mix between the masculine and the feminine in each of us is very variable

There are so many answers regarding sex and gender. There are only 2 biological sexes but and number of genders that people can identify as.

there is 3 genders the male gender female gender and transgender

Biologically 2 Genders in the Human Species. Anyone who says they are an animal they have initiated a mental disorder on their own.
