I LOVE talking Sex with my 7- and 5-year old daughters. No awkwardness there. Never… Case in point:
Isabella (she’s the five-year old): Daddy, did you know that boys have a Penis?
Me: Surprisingly… Yes, I did.
Iz: And, did you know I step on yours a lot in the hot tub.
Me: That did not escape my attention.
Iz: And, did you know that girls have a Vagina.
Me: Yes, Sweetie. In fact I think I taught you that word… What was I thinking (but you asked what it was)?
Iz: And, did you know that girls paint their fingernails and toenails sometimes.
Me: Well, yes they do.
Iz: And, girls will put earrings on and wear dresses. Boys don’t do that, they wear pants.
Me: Yes, you’re right.
Iz: And girls like dolls and playing dress-up? Boys like to fight.
Me: Yeah. I suppose.
Iz: Daddy… I REALLY like being a girl.
Yay for her! NO BOYS!
