Tickling fetishism is a sexual fetish in which participants derive sexual stimulation from tickling, or being tickled by, another person. Erotic tickling may involve the physical restraint of a submissive by a dominant. Although technically a BDSM activity, tickling is not fully recognised by the community and is relatively unknown in the mainstream.in dominance and submission scenarios, sexual partners may agree upon a safeword to signal that the tickling should stop.Different individuals may find tickling of virtually any region of the body to be pleasurable, and this fetish can also involve excitement just from watching others being tickled.
