I read the full list, and I did not find any "tickling" fantasy nor "foot" fantasy, so I assume that they did not even thought about it. Perhaps it is not something "interesting" for them, or perhaps they don't think it is sexual, or perhaps they think that tickling is too common to be even considered a special fantasy. And I actually think that tickling is not actually sexual unless something else sexual is happening, like tickling naked, tickling genitalia, tickling while stimulating, etcetera.
What really surprises me is that they did not include the feet fantasies, I think this "fetish" is actually more common, perhaps too common to be considered something "strange". I bet that feet are the fourth thing that excites people besides face, buttocks, and breasts. And it would have been very interesting to discover that with a poll like this one. If you know one please handle it to me, as all I have found are the typical questions in forums asking "would you let your partner touch your feet while having sex?".
And, it is strange that "having sex with someone younger" is not at the top of the fantasies, I actually believe this is the most common fantasy, perhaps in pair with fantasies about the loved one.
