sensual tickling

Erotic sensation play is a class of activities meant to impart physical sensations upon a partner, as opposed to mental forms of erotic play such as power exchange or sexual roleplaying.
Sensation play can be sensual, where the sensations are generally pleasing and light. Many couples that would not consider themselves active in BDSM are familiar with this kind of play: the use of silk scarves, feathers, ice, massage oils, and other similar implements.
Sensation play in BDSM can also involve sadomasochistic play, involving the application of carefully controlled stimuli to the human body so that it reacts as if it were actually hurt. While this can involve the infliction of actual pain, it is usually done in order to release pleasurable endorphins, creating a sensation somewhat like runner's high or the afterglow of orgasm.
