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.

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.

General scenarios are placing the person in a situation where they are exposed to heat and cold conditions more directly.

Safety precautions should be used which are appropriate for the materials, techniques and body parts involved.

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.

Fire play is usually considered a form of edge play - frequently exciting, but with significant dangers. Unlike other forms of edge play (extreme rough body play, blood play, interrogations, abductions, etc.), fire play scenes tend to look kinder and gentler; although it can be dramatic, the sensations inflicted in most fire play scenes aren't actually painful (much like hot wax play or sensation play). Fire play also rarely leaves marks on the skin - though some people deliberately burn the skin slightly to leave it red and irritated.

The two most common fire play techniques are bouncing and streaking. In bouncing, lit fire wands (sometimes called batons; essentially a small torch) are bounced along the skin. This may or may not involve transfer of burning fuel.
