Tickling as a fetish is perhaps one of the most common human behaviors known, in that studies indicate nearly 85 percent of adults in some way or another enjoy tickling others, being tickled themselves, or watching others be tickled.
Apart from these general attitudes from tickling, forced laughter by tickling can also be found in the sexual fetish world of BDSM. Those who gain sexual pleasure from tickling and/or being tickled are known to have a tickling fetish. Those who seek tickling out, and who gain pleasurable excitement from tickling and/or being tickled are known to have a "Tickling Fixation". Tickle fetishes involving "erotic tickling" (frequent breaks, safewords, sensual movements), using fingers to tickle areas such as the ribs or feet, using the tongue to lick the face, soles of the feet and toes or items such as feathers and brushes to produce tickling sensations as part of erotic foreplay.
There is even a form of online tickling through a messaging client known as cyber-tickling, much like role-playing, but the reactions are pretend and transcribed.
