Happened to me waaaay before high school.
When I was in high school, I saw my friends tickling each other, and I always felt funny down there. As a result, whenever I saw someone getting tickled, I would look away as fast as I could. Can anyone relate? 😱
Oh......
I can relate, up to the point of looking away. I couldn't look away.

What is there to elaborate? 🙂
What were the circumstances that led you to know yourself to be a tickle-phile?
Because, in some strange way, it seems as if for many of us, the tickling attraction, was developed long before the sexual feelings
