Sister asking about sexual things.
My 12 year old sister has been asking me some peculiar questions as of late about my sexual preferences and things about parts of her body.. I've asked why she wants to know and she replies that she is just curious but it's getting to the point where I am beginning to believe that its something more than "just curiosity". I'm just worried that the situation could manifest into something worse.
Is this normal for a 12 year old to be asking these sort of things?
