Does this sound like my meuse enjoys tickling me & is my request acceptable?

It does seem that your friend enjoys tickling you. There's nothing wrong with that. You're right when you say that tickling can be an effective therapy. It doesn't work for every one but from what you've told me it sounds like the chances it would work for you are very good. Give it a shot. I don't see anything wrong with asking your friend to tickle you (seeing as how she appears to enjoy tickling you anyhow). It sounds to me like she would be very likely to accommodate you. I would suggest you have her give you a really good foot and tummy tickling. I hope it works and you feel better. Happy tickling.
