This is something I would never do, no matter how tempting, due to the harrassment laws. I probably have posted this on here before, but a few years ago, I was reading an article called "News Of The Weird" where a guy with a fetish for sweaty female feet, called several girls up, and asked them if they had sweaty feet. He ended up getting a year in jail for phone harrassment.
I can see the novelty, and the temptation, in doing such a thing, to call random girls, and ask them if they are ticklish. However, with all the sex harrassment laws, I consider doing such a very unwise move. I prefer to confine discussion of tickling to girls on TMF, since this is the subject matter of the site. Heck, I got a warning from AOL a few years back for asking girls tickle questions in one of their general chat rooms. That was enough of an eye opener to confine my tickling interest to here. I wouldnt like to add a court appearance, or jail sentence, because the cops trace my number, if I called some random girl, and asked her if she was ticklish, not worth the risk.
