Well, it's not as cut and dry as that.....
I am all for taunting and talk, but I'm extremely picky one WHAT I find invigorating and overwhelming, and what is just irritating (BAD for me when it comes to tickling, cos if I'm irritated, I get awkward and restless and the fun goes away).
I'm a sensualist, but I'm also an intellectual, and in BDSM circles, IF I was into more than just tickling, I would be known as a "switch". For this reason, I 100% LOVE the mind-game taunting type, either when 'ler or'lee. Nothing makes me feel helpless and go crazy like explaining what is about to happen next, asking which places tickle more extremely, or simply the phrase, "Now, then... what if I did... THIS?" *shudder* Not truly proper without those kinds of statements. Stating the obvious (Boy, you ARE ticklish here... even more than I thought!) also works wonders.
I am NOT into belittling, or power-plays, however... so I actually, myself, find the "baby-talk" types of taunting take away from the overall effect. ANYBODY can usually tickle a child... I like being reminded how vulnerable- and human- I am even though I'm an adult. Adds to the intensity for me.
So I have no real middle-ground. I love the mind-games, but I absolutely LOATHE baby-talk... go figure I'd be the finicky one.
Thought I'd throw out a different response. 😉
