I've been tickling men since I was 5 years old. If I had to total all the guys I've tickled during my lifetime so far, I would have to say it's been close to 100, and I'm trying to be as conservative as possible. (BTW, this is totaling all instances, from friendly quick rib pokes to tie and tickle sessions). I've always been physically friendly with men I've befriended (a very important point--no stranger tickling). To be able to do that, I had to, of course, gain trust. And this is sincere, because I do truly love my male friends. I care deeply about them and enjoy the time we've spent together. It's really too bad that life gets in the way of good friendships, but that's another topic for another time.
The point of that entire paragraph is to state that I think men's desire for fun, physical contact with other men through tickling has always been there. It's only in recent years, thanks to the internet, that those desires have surfaced publicly through forums and chats. Many m/m tickle enthusiasts had felt isolated and alone--some still do. So the emergence of m/m tickling videos and sites seem like a floodgate of sudden acceptance to many and, to help with the intensity of that openness, I'm drawn to helping guys overcome anxiety about their m/m tickling desires.
