The official terminology for tickling fetishism is known as knismolagnia which is an arousal derived from tickling someone or the sensation of being tickled themselves. As far as fetishes go, knismolagnia is said to be one of the “most obscure” , and least researched of the paraphilias. However, people who have it often prefer tickling over other sexual activities including intercourse. Some people can orgasm from tickling pleasure alone. Others don’t even need to be touched and can get turned on just by watching someone get tickled or by tickling someone else.
