First of, welcome to the TMF bro. I hope you enjoy your stay and stick around. Now to the topic on hand. Welcome to being an 18 year old with a tickle fetish. It feels embarrassing and awkward. I have to ask though, why is going out and socializing not an option? If you want to try on here its fine but honestly you're better off interacting in the community and writing stuff in posts or talking in the chatroom, then you are in the personals. I'm sure that over the period of 18 years or so since this place existed, that there have been successful meetings through the personal sections that weren't MUNCH/Gathering related, but probably not many. I dated a girl from here for awhile and it wasn't from the personal section. I just noticed her saying something interesting in a post and shot her a message and a friend request. Guys here do horribly because since they assume its a fetish forum they can go balls deep and talk about tickling right away. They don't understand that the gates to complete fetish satisfaction, that 100% tickle saturation...is right behind this door with a lock on it. How do you open that lock? Not by trying to shove your dick in it("ZOMG YOURE SO CUTE LEMME SEE YOUR FEETTTSSS WHERE TU TKLSH LOL") but by taking the time to get to know the person they are. Talking to them about interests or current events. Its easy to know if you click or not. Then comes the picture exchange to make sure you aren't being catfished. I was catfished in my earlier years and it sucks. Once you two crazy kids decide you like each other maybe the ticking subject is finally broached. From there arranged meets etc etc. The thing is, its exactly the same in real life.
Your 18 and its embarrassing. Theres no need to come right out with it right away when you're getting to know a girl. At a younger age like yours, success with "vanillas" comes from dating them the way you would date a woman if you didn't have a tickle fetish, but instead just throw a little tickling in and no one is the wiser. I wasn't up-front with potential girlfriends about my fetish until I was about 24...that was just the year I figured out I wasn't embarrassed by it anymore. That year is different for different people. Now a days since I'm a little older(34) I know exactly what I want and I let a girl know within the first couple of conversations. At my age you don't really want to waste your time only to find out that the woman isn't ticklish or HATES being tickled. But at 18 years old...holy hell man. IF its an option just go out and socialize. 99% of my tickling adventures up until age 18 came from girls I knew from high school. Its out there my friend. Don't think of your fetish like some big, ugly, embarrassing monster that everyone laughs at you about. Think about it as you being truly more unique then 99% of the people around you all the time. Its kind of cool when you think about it that way. Good luck man and feel free to ask these kind of questions throughout the community. There are thousands of guys on this forum that have gone through the exact same thing that you're going through right now. I guess when we are all old men and mainlining Viagra we will pass the torch and guys like you will lead on the younger generation of us perverted tickler/tickleess.
