So you know how girls have private parts just like boys do? Well, the outside part that you can see is called the vulva. Sometimes artists like to draw or paint pictures of people, including girls, and some of those pictures might show the vulva.
And you know how the vulva is a part of the vagina? The vagina is actually inside the body and you can't see it from the outside. But sometimes artists might draw a picture of a girl where you can see some of the inside of her body and that might include the vagina.
It's important to remember that not all pictures of girls or women will show these private parts and it's always important to ask an adult if you're not sure if it's appropriate to look at or not. But sometimes in art, people like to show different parts of the body to express different things or to just make a pretty picture.
