Let's talk about sex

As we were talking home from school, Gwenchik asked

Gwen: What is sex?

Me: Why do you ask?

Gwen: Everyone at school says that it is disgusting.

Me: Well it is not. It is a physical expression of love -- for example when people hug or kiss...

Gwen: Yes, they were right, it is disgusting! Do not tell me anymore.

.....

Hmm, when do you start talking to your kids about sex?

Kissing

Gwenchik saw us kissing and wondered why other parents kiss their kids on the lips and we do not.
Me: When you grow up and marry, you can kiss your husband on the lips.
Gwen: I only want to marry Daddy! And you said that I can't, because he will have to go to prison. And it is so hard to find a husband.
Me: Do not worry about it now, it is a bit early for that.
Gwen: You know, I do not need a husband. I'll just live with Lina or Jasmin or Nastya (her girlfriends) and we would have a daughter and can kiss anyway we like!

Troubadour

Gwenchik was listening to a story about a princess that run away with a troubadour and left the King...
Gwen: The princess ran away with troubadour because she really loves him. But she left her Papa.
Me: What should she have done?
Gwen: She should have kissed and hugged Papa goodbye and promised to come and visit, than she could run away with the troubadour
