"Contrast play"

Not sure if there's a term for it, but I find that I'm pretty into contrast when it comes to tickling and ticklishness.

For example, when a person's ticklishness jumps from a 2 to a 10 when going from socks to nylons.

Or, a completely not ticklish person being tickled followed by an extremely ticklish person. Like in this clip: youtube.com/watch?v=e8k8H3OgpB0

Does anyone like this as well, and/or can think of any clips?

Oh I definitely have some clips like that! Namely my belly-focused ones, where it goes from soft relaxing feathers to me screaming lol
