Well, to answer the question in this image:
A little girl walks into the bathroom and sees her mother getting out of the shower. She points at her mom's pubic hair and says: "Mommy, what's that?"
"It's my pubic hair," the mom says. "You'll get this when you're older."
The daughter nods her head and points at her mom's boobs, and then asks: "Mommy, what are those?"
"These are my breasts," the mom replies. "You'll get them too, when you're older."
The next morning, the daughter walks into the bathroom and sees her dad getting out of the shower. She points at his p**is and asks: "Daddy, what's that?"
"It's my p**is," the father replies.
"When am I going to get that?" the daughter asks.
"As soon as your mother leaves for work."
