Thank you all. I can see that some of us are in the same boat. 
Thank you for the link, Barney'sMom. I read it and it was very interesting.
My difficult child is still into PS2 and computer games, and sports. I am hoping we can keep him on grade level in school and he can have a career of some sort in one of those areas. It seems strange to plan ahead, but as with-most kids, you try out diff things with-them and see what fits. My parents figured out very early that I loved art, for ex.
Same for my daughter.
Trinity, if you have found any solutions for the sexual obsessions, please PM me. We are, indeed, still dealing with-that. I am concerned that it will get difficult child beaten up or get the police involved. I am worried to let him stay at overnight at other people's houses for fear he may bring something home. Bad enough when a kid swipes a pkg of gum or even an Ipod, but when it's something that personal, you wonder whether the person will notice it's missing and whether it belongs to someone else. It puts us in a very difficult situation.
I wish I could get into his head and figure out what is going on. We made some progress a few mo's ago, and thought we'd gotten over it. Not so.
Back to the drawing board.
Why couldn't he have come up with-an obsession for sugar packets or something?
Daisyface, scary about the tornado. I know people try to go back into burning houses to retrieve pets and such, but you never know when or where a tornado will hit. I'm sorry you had to go through that.
We need to come up with-a plan for our dog and cats. I'm glad I had this reminder!
