Sigh.... Yes.
Younger me has been guilty of crossing the line more than once (and it has gotten me into trouble). This is well before I learned about the rules of negotiation/ consent and well before I knew what a fetish even was. As I have said in a couple of prior posts, I have run into those people in later years, and the first thing they say is, "Do you remember when you used to tickle the hell out of me?" It is pretty embarrassing, and I do feel guilty about it, still. I usually change the subject immediately to something they are genuinely excited about telling me. Thank goodness, they chatter along and don't circle back to the times when I was a known tickle monster.
Sometimes, I can sense when one or two of them want to ask if I still do that- Tickle people relentlessly. But they are too shy to ask, and I am not about to prompt them. (Although one guy pestered me so much that I almost said, "SAY IT! ASK YOUR QUESTION!!!" 😅) He never was brave enough to ask, and I was never brave enough to get him to ask. He was an "ex-boyfriend" of mine. Lawd- I tickled him so, so, so, so much.
I don't do that now- tickle torture without expressed permission. And it is actually difficult for me to truly unleash that side of myself even when allowed. It is very hard to rein her back in.
On the other hand.... When operating as a lee and with careful negotiation, I do enjoy being taken past all of my ticklish limits (CNC). I don't ask for this or expect it in most sessions as I know that it does mess with the tickler. And I have learned to respect that fact that this is not everyone's cup of tea. Not every tickler desires to "break" a ticklee into pieces. Most enjoy the playful side. So... I play in a way that makes them most comfortable.
It is always nice to run into that rare tickler who gives me the tickle karma that I desire and deserve.
