Tickling games are interpersonal or social activities involving the tickling of one person by another. Some people find tickling to not only be a pleasurable experience, but also an erotic one. They may be sexually excited by being tickled or by tickling another person, some people like being tickled on their genitals, their waist, their feet, their underarms, their anus or their breasts while others prefer to tickle and some like doing both. Some engage in tickling games as part of a social act.


Knismolagnia is the experience of “arousal from tickling”. Acarophilia, often confused with knismolagnia, refers to arousal from scratching.

Excessive tickling has been described as a primary sexual obsession and, under these circumstances, is sometimes considered a form of fetishism, People whose sexuality is based almost solely on tickling can be said to have a tickling fixation. This fixation may also exist outside of sexual contexts.
