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.
