Years before I joined this site, my closest friend (alone) knew the details of my interest in tickling; two other friends had a hint.
I joined this place a couple of months ago, and I have since told three additional people and confirmed the details with the two who had a hint.
Sadly, none of the people I have told shares my interest, although they are all O.K. with it. Four of the six are gay men and one is a bisexual woman; they all know what it is like to have sexuality in the closet and are very supportive.
The other friend, a straight guy, gets a kick out of Yaqi on Howard Stern; I knew he would have no problem with my interest--and, indeed, he had a million questions when I told him. Ironically, though, he would never so much as tickle his wife, as he hates tickling.
I do not know anyone beyond these six whom I can tell.
It is honestly like coming out of the closet again. It took me years to accept that I was gay, and now I have been out as a sexual gay man for more than a decade. And now I have to accept a fetish. Not an easy task for someone who is otherwise as vanilla as can be.
I was in denial about tickling until I found Jack's Rack (a gay site) on line in 1999. At that point I knew that I had this fetish and could no longer fool myself. It took me until this year to tell anyone beyond my closest friend, and to this date my tickle experiences are all ten second stints during foreplay and, when I was younger, horsing around.
I e-mail a couple of people from this site, and it feels very good to talk to people who understand what I am saying. My friends are supportive, but it would be like their telling me that they were sexually attracted to broccoli. I'd be supportive and non-judgmental, and I'd let them talk about broccoli as much as they wanted--but I would not get it.
