Vulva
The vulva is the external (on the outside of the body) genitalia (genitals) of a girl. It's located below the bottom of the stomach between the legs. The vulva consists of the mons pubis?, labia majora (outer lips), labia minora (inner lips), clitoris and the exit of the urethra? (pee hole). The entrance to the vagina is also in the vulva. The outside of the vulva, I mean outside of the labia majora, and the rest of the crotch area is usually covered with pubic hair in adolescents? and adults?.
The vulva is often called the vagina, but the vagina is internal (on the inside of the body). We've got to get the word out for better sex education and sex, vulva for girls' external genitals!

You can't just go around the rest of your life using 'vagina' as an all-encompassing term for everything between your legs. That's... That's like calling your face your throat." — Matthew Broussard on Conan O'Brien
