I would answer the questions without too much detail. As or if she makes further inquiry, you can add more detail till she is satisfied that her questions have been answered. She may be hearing things from these peers who are doing all the chasing and kissing. And you do want to be the one who explains the facts of life to her, not her little friends.

Having said that, I would also suggest that you analyze who these friends are, where they are having these discusions, and see if you can dilute that relationship.

I remember deciding my daughter was hearing the wrong conversations at about 9 years old, and then learned that her new friend had a much older teen sister, who would include the little girls in the chats she and her friends had. I decided that her friend could play here at our house, but not at the friend's house. The teens were very nice to the girls, but their topics were waaaay to mature for them.

Don't worry about high school yet. There are a lot of 16 year old girls in their last year. You daughter may be one that matures physically earlier than others her age. In which case she will fit in better with the other older ones.

But for now, play it one day at a time. Today she is very curious. Next week, she may be interested in something entirely different. Don't avoid the questions. A good book store would probably have something on her reading level that would be exactly right. It would be worth your while to check on it.

While you answer her questions, it would be a good idea to try and find out what her friends are saying on the subject. Then, if someone is repeating stupid and harmful information (you know the kind, "you can't get pregnant the first time") you can steer her in the right direction. And at the same time find out if there is a single source for this interest. Just casually ask..."what do your friends tell you?" You say she is intellectually advanced so she will understand that you are not snooping, but that you just want to be sure that she is getting correct information.

Keep in mind that some of her friends may start their periods when they are 9 years old and get pregnant by 10.

Yes, today's females are developing much earlier than previous generations. I meant to also suggest a book called "What's Happening to Me?" Check it out at the local bookstore. We bought it in paperback; don't know if it comes in hardback. Read through it and see if it is what you could use right now. We sat down on a quiet day and read it together. Then I was able to answer any questions--while dad had her brothers out of the house.
