Belly Button Art Tickling Poking and Playing with my Stomach Part 2

Description: Part two of two: exploring the sensitivity of my belly button. i have always been blessed/cursed with hypersensitivity. my belly button is just one of many tickle spots that gets me excited. self stimulation is not nearly as fun as playing with others but for now i'm using the tools i have around to explore. writing on my body felt kind of silly at first but i am an artsy one. what other tools should i try?
