I am very ticklish. This is my weakness.
When I was little, this was awful. I got tickle tortured my some of my older relatives and it left me in tears and pain. Very uncool.
Later on down the track, I've known some people who give nice tickles, ones that are much gentler and softer than those tortuous ones I got as a little kid. I don't mind these softer ones, it makes me wriggle like a mad thing, but being in the arms of a loved one makes it much, much more fun.
I'm glad that very few people know the extent of my tickleishness. It's something that could definitely be used against me.
