When you were born, you were labelled as a girl or boy – this is your sex. People born with a penis are male, people born with a vagina are female. As children grow up, their family, school and even the media show how to be a girl or a boy. This includes the clothes you wear, the toys you play with, or the jobs men and women should have. This is how people develop their gender as they feel like a girl/woman or boy/man. It’s Ok if you don’t identify with any sex or gender. This is called gender non-binary or non-conforming.
