Mustang, I agree with your first opinion, but NOT with this one.
And I also cannot agree with Sammy.
I told one of my best friends about my tickling fetish, in a very "natural" way: I suddenly showed him a tickling site I like, without doing or saying anything strange to him. I thought that maybe he will like that too, because he also loves to tickle women.
But the result was something totally else......
He laughed at me the whole day, and tried to speak off me of this fetish. The one nice thing was that he didn't ever made fun of me in front of others.
I didn't care about his opinion, but it felt BAD. After this I told him about I haven't given up on the tickling fetish and I never will.
My girlfriend and my ex-girfriends were much more appreciative. They know I love tickling, and they loved/love it too 😀
What I'm trying to say is that you shouldn't be so open about a tickling fetish at lots of people, except your partner or a close friend, because they may see you as a freak in the future. And believe me, in my eyes you are absolutely no freaks, but in usual people's eyes you can easily be.
