I have used Facebook a couple of times as a reach-out to try to discern if any of my lady friends might share the fetish. Just a couple of innocuous posts a few months apart, but I had hoped that someone with the fetish would recognize it for what it was.
I never took it any farther than that, or created tickling personas. I had wondered what I would do if what happened to you happened to me...
And my answer is - nothing. I wouldn't do anything different, or even worse, expose myself as doing this nefariously. I would just continue on as if nothing had happened and probably wouldn't go any further than you have with my tickling persona.
Probably..
