Preteen is young, but is she menstruating yet? How old is the boy? What have you decided about birth control?

You are right. This is awkward but there are the practical matters to consider as I don't think you are going to try to put the genie back in the bottle. What decisions have you made regarding her life with you between now and 18?

This is one of those instances where a family or group counselor might be your best bet. That is where I would go with this complication. When I read your post it shook me, not because of the sex, but because of the effect it is having on the adults in the situation. Any parent would be stunned.

You should, however, feel very proud of yourself for recognizing that this was consensual. You are over half way toward dealing with the situation effectively. Her being too young for sex is more a social construct than a physical issue in that your doctor said her body is capable. Pat yourself on the back for being concerned and approaching this in as orderly a fashion as possible.
