SexMaleOrFemale
Your sex is whether you're male or female. Generally speaking, males have penises and testicles and females have vulvas and vaginas. In biology males have the sperm and females have the eggs. Normally males have XY chromosomes? and women have XX chromosomes?.
A child male is called a boy and a child female is called a girl. An adult? male is called a man? and an adult female is called a woman. Boys are different, usually, from girls in more ways than just different genitals. Boys tend to be more adventurous and aggressive, and girls tend to be quieter and more social. Men grow bigger and taller than women and have a lot more upper body strength. Women grow curvier and grow breasts and are usually a lot more beautiful. These are just a few examples of the differences between men and women, there are a lot more.
I'm told there's extremely rare conditions where it's difficult to tell if someone is male or female, but for most cases it's clear.
