Except that's a form of syndrome, not a gender per se. All other forms of the XY chromosome composition are genetic diversions that are not "meant" to happen biologically speaking. You don't get a third form of sex that's unique, but rather some form in between that's usually sterile. Humans are genetically designed to either have a penis or vagina and all other forms, strictly biologically speaking, are defects. I feel like people didn't pay attention in school.
I'm not saying they don't exist, simply that they are not their own sex since its a genetic defect and not a human "feature". Of course they still exist and have worth as people. But in their case it becomes more of a question of gender rather than sex. Especially when they have both a penis and a vagina.
I thought it was that we have lots of genders but not many sexes? Because if you put the wrong sex on medical sheets and can be pretty bad or something?
