Hypnotism. Hypnotism generally refers to a form of BDSM play which involves
the actual or simulated placement of a person into a hypnotic or highly
suggestible trance-like state, during which he or she may be instructed to act out
imagined sexual or erotic scenarios. (See also: Age Play, Infantilism,
Kidnapping Fantasy, Knife Play, Rape Fantasy, etc.)
Ice Play. Ice play refers to any BDSM play activity that utilizes ice to enhance
erotic sensations, produce discomfort or pain, or even to startle a play partner.
Ice play can range from the very simple act of running an ice cube over a
person’s erogenous zones, to very complex and potentially dangerous activities,
such as the use of ice dildos. (See also: Sensation Play)
Immobilization. Immobilization refers to any BDSM activity that involves
rendering a person immobile. This usually accomplished through various forms
of bondage, but can also include other means, such as mental bondage,
forniphilia, queening/smothering, or forcibly being held down. (See also:

Impact Play. Impact play is a generic term which refers to virtually any BDSM
activity that involves striking, such as spanking, slapping, caning, paddling,
whipping, or cropping. (See also: Caning, Crops, Flogging, OTK spanking,

Infantilism. Infantilism is sometimes referred to as Adult Baby/Diaper Lover
(AB/DL) play. Infantilism in BDSM usually refers to the derivation of pleasure
from fantasies and role play involving a return to infancy. This typically
involves exhibiting baby-like behavior, such as wearing (and soiling) diapers,
drinking from baby bottles, sucking on pacifiers, sleeping in cribs, and similar
activities. Scenes involving infantilism generally requires another person, in
addition to the “baby,” who assumes the role of a parent, caretaker, babysitter,
and on rare occasions, another infant. The infantilism play may or may not be
sexual in nature, as is the case with most kinds of age play. (See also: AB/DL,
