3, but one somehow became a ler herself. Considering she was always my lee, I don't get that one. One had an interest in BDSM and never considered tickling before I met her. The third, I think was just waiting to have her feet tickled in a more private surrounding. She was a ticklephile just waiting to realize it, because the first time I tickled those feet, she was turned ON.
Oh wait, 4. I forgot about my girl I had in Columbus. She wasn't exceptionally ticklish (not for very long anyway), but was a great tickle top. She got hooked, and has told me a few times about her trying to get guys since me into it.
Most of the rest just thought it was fun, and didn't really "convert".
