I'd have to agree with what everyone else has said...depends on the person, depends on the spot. I never used to be "licklish" (I found this out after a few attempts were made), but after a while someone tried it and it worked! A lot! However, it only works for me personally in a couple of spots - feet, tummy area and belly button to be specific. But under my arms, my thighs, etc...nothing. So many variables to consider that prevent it from being a blanket "yes or no" answer. And (from my own personal experience), if done in the right way, lick tickles can be one hell of a turn on in their own right!
