This might have been mentioned, but...when people start talking about when they were tickled by their family members when they were younger. Not just in passing, but they have these elaborate stories of getting tied up. It's just weird.
f/f. makes me ill, and most others find it to be a turn on.

Just curious ... Why?
Gotta say, for a guy who considers it "none of his god damn business" if his sister decides to be a prostitute, it's a little odd that you'd be bothered by one person you've never met asking another person you've never met whether or not they're ticklish.
What about if people ask google whether or not a given celebrity is ticklish?
