What are some of the different tickling positions you have noticed the lee in? Are there any that seemed to make the lee seeming more ticklish then they otherwise would be?
Speaking personally as a Lee, the hog-tie position is very intense for me and has resulted as the most tickle frenzied experience for me. I'm really ticklish on my stomach and that position makes my abs flex and leaves me completely vulnerable without being able to move an inch.
I don't know if you can tell from this image, whonose, but I was tied so tight spread-eagle in this last session, my abs were engaged. I mean like I was exercising or something. So as he tickled me, my abs engaged more and more, giving me this ab exercise soreness.
