For those of you who have read my stories, you know my favorite self-tickling toy is my old turntable. Not a stereo, or anything fancy, just a cheap, plastic record player. I removed the top, tone arm, and such. Then I attatched feathers to the spindle and turntable. Placing the feathers against my feet, (the player on it's side, so the feathers sweep up, or down,depending on which side it's on.) and switching it on by remote control tickles me terribly! (Not that it's REALLY terrible!) 🙂 With three speeds (33 1/3, 45, and 78) I can choose a nice slow session, a fast paced one (Dropped the remote on/off switch on one of those once. Thought I was going to tickle myself to death) or something in between. So, yes, it IS possible to tickle yourself, I suppose much of ot depending on how much control you have, and how ticklish you are.
