I was subjected to this when I was younger; interestingly, it became a diversion from adult stressors later because I remembered that I was tickled to the point of seeing stars and having my mind go blank, something like a natural high that I crave on a regular basis now.
I like to slip off my sandals and put my feet up on a chair when I’m at lunch at work; I also wear toe rings and shiny anklets with capri pants to help emphasize how barefoot I am, and I get a secret thrill from strangers seeing my soles and imagining them tickling my feet. There I said it...
