A combination of both usually works best. Once the 'lee gets used to one sensation, you change things up to "keep things fresh".
But at heart, I am a finger tickler.
I agree with the posters before me. I think Fingers, tongues and teeth work best, but occasionly useing a feather or small brush or q-tip would do wonders as well. But with me, fingers, teeth and tongues are all that is needed.
As a wise person once said...Variety is the spice of life.
But if I had to choose, I'd go with fingers. It seems to give more of a personal connection when you're actually touching the other person and a more sensual experience. Tools make it seem more like you're "operating" on the person in a way.
Fingers and mouth are No. 1 and No. 2, but there's something to say for vibrating tools on lotioned flesh (except for the stupid toothbrushes). Those three-prong massagers you get in drugstore checkout lines--use them on lotioned soles, then brace for Vesuvius.
I'm typically a finger tickler, since it means I can adjust my technique to exploit a lee's weaknesses. An electric toothbrush works in 'certain situations' though
I wish our NIH grant would be approved so we could really settle this ?
Yeah, chainsaws and dropcloths are way overrated. The 'lee becomes desensitized almost instantly....... :0 Skilled fingernails and fingers are most useful and versitile. I do also enjoy using toys for variety and keeping the 'lee sensitive and guessing. I have had good luck with Sonicares, especially beneath and between da toes. Of course tongues, teeth, pipe cleaners, a piece of nylon hose and even feather are great on/under/around toes too.
