Are there more than 2 genders or sexes?

Jul 11, 20

The feeling of belonging to genders other than male or female is due to gender dysphoria (not the actual existence of other genders).

A key component of gender dysphoria is the distress that comes from one's body and gender identity not matching. This feeling has been associated with decreased insular and prefrontal cortical volumes (of the brain)—the insular cortex is the possible foundation of body awareness.
