When I first met the woman who is now my wife, I wasn't into tickling and I knew nothing about the tickling fetish. After we had been dating a few months, she told me "I like to be tickled". And I replied something like "Oh, that's nice.", and she told me "No I really like to be tickled."
I was a bit dense, and it took me a while to really understand, but eventually I realized how important tickling was to her. I'm pretty open minded, and I had no preconcieved notions about tickling, so I was perfectly happy to incorporate it into our play. And it was great! I get a lot of pleasure from giving pleasure to others, so tickling her is a great experience.
So, I can certainly say I like tickling, even though I don't like it quite the same way that most people on this forum do. If I didn't, things probably never would have worked out between her and I, and she would never have become my wife.
After introducing me to her fetish, she starting bringing me to gatherings as well. Since then she and I have attended many munches and gatherings, and now a significant number of my circle of friends are tickle-philes and their other kinky friends, whom I would never otherwise have met.
It is safe to say that if I didn't like tickling, my life would be very different.
