'I'm a non-binary 10-year-old'

As a human God has created us with a sex.  but some human who has a sex but they would change their sex because they feel that is not their self. maybe if he is a man but in his self is a girl and he act like a girl not a woman so that's why he would decided to change his sex. non-binary.

 Non-binary people are those who don't feel male or female. They may feel like both or like something in between. They may have a gender that changes over time or they may not relate to gender at all.

 as a human I believe that God has a plan for me and that's why he created me as a woman. maybe sometimes people do not know what is their purpose of their life and they think that with change their sex they would have the puprpose of their life.
