This is a bit of a tangent but I didn't feel it really deserved it's own new thread entirely so here we go:

Speaking of implements, when it comes to tickling I'm not wildly excited by anything other than a person's fingers. And in fact if someone's tickling me, I like the contact.

Feathers seem to be super popular in stories, but they give a light tickling like an insect is crawling on you that makes you want to sort of flinch a little. They can't give that deep hysterical tickle. Electric toothbrushes is another one I've never cared for really.

I'm also not really into foot tickling but that's one that seems to come with a lot of using brushes to scrub feet. Honestly, I find I am most ticklish even there if people just use their fingers.
