coming to terms with these desires she may be having can be a frustrating thing for her. A few people mentioned the stories here, I would agree with this completely. I actually have my girl read a story a day, and give me a brief commentary on the story. I take note of things she likes and does, I also learn a few new tricks myself.

Adding to the clothing thing you've done, go to the local thift store and buy some extra clothing as "house" clothes. This way you have plenty of cheap garments you can cut/ripp/tear at without concern.

The journal idea is another thing I require as well and has always worked well.
