Activities that manipulate the five senses. Some activities are for stimulation and involve creating a new or uncommon experience for the senses. The use of pain stimulation such as spanking or nipple clamps is referred to as S&M (Sadomasochism). Another way to stimulate the senses is inducing a feeling of pleasure; for example, with a vibrator. Some other activities are for sensory deprivation and involve restricting the player's senses, such as the use of a blindfold. The scope of this sexual exploration is never-ending; people are always coming up with new ways to play. Hot wax, ice, whips, incense, ball gags, feather dusters, and just about anything else you can think of can be used for sensation play.
