I agree with Bella. It is a worthwhile and interesting topic. I find the demographics of tickling fascinating. So far I've observed, as mentioned in this and previous posts, that:
1) There are more male lers and more female lees.
2) Big folks, or at least big girls, tend to comprise a disproportionate amount of the tickling population.
3) Just looking at the TMF personals section shows you that most people into tickling are on the coasts, not in the middle of the country.
There's a 4th trend I've noticed, but I haven't heard anyone talk about it, and that's a cultural difference in tickling. Back in high school when I was first discovering my tickling fetish, there was this group of African-American girls who loved to go around and gang-tickle the guys. To this day, I find that African-American girls are much more open to the topic of tickling than Caucasian girls. Anyone else notice such a difference?
