Female poll: Are the majority of you?

How is it that most women-ESPECIALLY ONES WITH LONGER NAILS-are experts at tickling? I've had females ask if i'm ticklish, i say no, but then they try(almost always in the ribs)and i CAN NEVER HOLD IT IN! How do you do that? Whenever i've tried to get ladies back, usually i can't. So are you all just experts at this? Damn! Not fair!
