I know strange isn't it? Never really done many exercises as she tends to do it via massage or breathing at the moment as I freak out a lot, but it never ceases to amaze me have a simple movement or touch can unlock some feelings. Like you say tip of the iceberg, but believe me you don't want stuff to overwhelm you. I've gone too fast before and it was a nightmare. Good luck with this. It sounds really interesting. Pm me if you fancy a chat.
