Temperature play
Temperature play is a form of BDSM sensual play where objects and substances are used to stimulate the body's neuroreceptors for heat and cold for sensual effect.
Temperature play in general
Substances can include water, oil, molten wax, ice, chocolate syrup, whipped cream, melted butter, chilled fresh fruit and steamed vegetables.
Objects can include cutlery, ball chains, necklaces and many others, often pre-heated in hot water or chilled in ice water.
Space heaters, radiators, and other sources of heat can also be used for stimulating sensory arousal with heat.
Blindfolds are often used to intensify the effects, and bondage can also amplify the experience.
Safety precautions should be used which are appropriate for the materials, techniques and body parts involved.
Specialized variants of temperature play
Fire play
Fire play is a form of temperature play that involves using flame on or very close to, the skin. The flame is typically on or applied with a fire wand (essentially a small torch), and frequently utilizes 70% isopropyl alcohol as fuel. Other common fire play toys include flaming gloves and flaming floggers; other common varieties of fuel include 91% isopropyl alcohol, mousse, hand sanitizer, super-proof rum, grain alcohol, and flash cotton. As with many forms of BDSM play, the "proper" tools, fuels, and safety guidelines are often in hot contention between players.
