Birds-and-the-bees talk happening earlier

According to a new survey published early this week, most children in the U.S. will first hear “the talk” about the birds and the bees by age 11 – much earlier than their parents had as teenagers. I’ve long forgotten when I had this talk with my daughters, who are now 25 and 23, but I’m curious. When do you think we ought to be having the talk sex talk?
