I'm glad someone brought that subject up. I was rather surprised that the use of that 'dirty' word is so rare here. I avoided to use it myself just to conform with the non written rules of this forum, but it seems to me rather weird that so many people get offended by that word. I don't know what you guys here do with those videos, but I'd be very surprised if it is not to get some sort of sexual stimulation... I am on a tickle fetishist forum, am I not?
If so, you have to admit that tickling clips are nothing but pornographic material: just look at several definitions of pornoraphy I found:
1)"material (as books or a photograph) that depicts erotic behavior and is intended to cause sexual excitement " (Encyclopaedia Britannica)
2)"Printed or visual material containing the explicit description or display of sexual organs or activity, intended to stimulate sexual excitement." (Oxford dictionary)
3)"Pornography (often abbreviated as "porn" or "porno" in informal usage) is the explicit portrayal of sexual subject matter for the purpose of sexual arousal." (Wikipaedia)
You don't have to exactly masturbate to those videos (even though it's pretty much what I do), as long as it is a sexually stimulating material to you, then it's porn in my book.
