I'm ticklish in all the usual places. I do have a couple of places that I sometimes get nervous about--the thought of a tickler focusing on them too much gets me a little, shall we say, weak in the knees. I'm not going to reveal out loud, though. Any tickler who wants to know them needs to try to find them herself. 😉
Unless it was a significant other, I wouldn't want the 'ler attacking any "private" places. Just the usual tickle spots, please.
