I suffered as a kid having a bigger sibling pin down and tickle me, and gawd they were merciless. Once they got a hold of my ribs or my feet it was game over. But I do love it with my BF tickles me. It's a love/hate thing really. The loss of control is really the worst thing about it, but it does make me laugh when I'm down. Tickling others is pretty fun though, as long as they don't kick you while doing it.
How ticklish are you? What are your tickle spots? Do you like or hate being tickled? A playful thing someone does to you, or unbearable torture?
