I agree that children should not be encouraged to grow up too fast, but discussing how to chat with the opposite sex, without feeling clumsy, etc, is not a bad thing.
And yes, as Victor says, these people are on the verge of adulthood ~ in some cultures they would be considered adult aready, and may be married even.
And much better to talk about things, than to worry, or worse, to do things one doesn't understand and isn't ready for and then get into trouble.
