I have been very "in the closet" with my fetish. Never have I actually came out and told anyone about it (well, there have been a few times when I have told people that I've met in chatrooms, but I don't really think that counts). One time an online friend picked up on it, though. She was on my MSN list, and she tended to like to have online pillow fights. I liked that, too (corny and immature, I know ha). It got to where I would often start them in hopes that they would lead to cyber tickling, which they usually did. One time after things turned to cyber tickling (she tickled me) she said to me, "Did you get your fix?" I asked her what she was talking about. To this, she answered, "Your TICKLING fix...the one you always come for!" I couldn't help but blush a little at that, but it all turned out okay. We have drifted apart somewhat, but we still talk on occasion.
As for the whole tickle fetish/foot fetish thing making a person weird, I have a some comments. First, as has been indicated, most tickle fetishists and foot fetishists seem to be harder on themselves than other people would be. Here's another thing: most sexual (as in sexually active or interested) people have certain things that "turn them on." Some guys might be turned on my a woman wearing boots or a woman with really long fingernails or whathaveyou. Women might have a thing for tall guys, or might like it when a guy touches them a certain way. When you consider it that way, there are possibly more fetishists out there than we realize.
Rest assured, I don't think you're a freak.
