The following conversation took place via text message:
Me: Do you know what a blow job is?
Lizzie: No. What is it?
Me: Well...it's when a girl kisses a boy's penis*
Lizzie: That sounds like oral sex.
Me: What do you know about oral sex?
Lizzie: Only that it involves mouth to penis interaction.
Me: It also involves mouth to vagina interaction. And you can get STDs from it.
Lizzie: Ew! Like AIDS or Scabies?
Me: Yes, like AIDS. Also, Gonorrhea, Syphilis, and Herpes.
Lizzie: I cannot imagine anyone at my school doing it.
Me: Well...some kids are doing it. And some boys might ask you or your friends to do it so now you know what it is.
Lizzie: Gross! I'm not doing that. I don't want scabies.
*Madhubby thinks I should have gone into more detail here but I think saying "kissing" was good enough to give her a visual.
