I've...never really noticed that...
But.
In this community, there may be a larger number of people who are "open minded" about different sexualities/sexual experiences, so that may be part of it?
Agreed, and actually, most here are straight, and a few are gay.
Many guys want girl on girl tickling, just because they don't want to see another dude in a tickle video, they could car less if the girls are gay or not.
And being a tickle fetish, I think most have to be honest and not-hypocritical like myself, and say "Look, there's no way in hell I can be fair and say gays are a bunch of weirdos....when I have a tickle fetish!"
Recently more clips have been produced that feature guy tickling, but that's just because a few new companies have risen up, and have posted clips, and are obviously welcomed along with the pantyhose/nylon tickling, barefoot tickling, French tickling, Czech tickling.....
It's just that in the past, most clips were bare foot and women being tickled. But then again, there were only about 4 or 5 companies in ALL. With variety comes more choices, and it just so happens that of very recently, the guy tickling is growing. I'm not into that, so I ignore it, but I think to myself, "Well, I'm happy that THOSE guys and gals who enjoy that now have something for them. I want everyone to be happy, and I'm glad they have their interests being met. Now let me go check out the newest nylon tickling clip from whoever decides to produce it, while they go check out Tickled Guy or something."
It'll never become overcome with gays, just as the nylon lovers will never overcome the forum, or the hogtied lovers will never "take over."
