Wax is another kind of sensation play in BDSM. Wax can be hot or warm. Because people have varying degrees of heat tolerance on different areas of their body, one of the safest ways to start wax play is by experimenting with yourself first.
Body Prep
You can prepare your body for wax play by dousing yourself with lotion or mineral oil to make wax removal easier after play. Mineral oil can be particularly helpful for those who have more body hair. If you can, it would do to shave or make your body feel smoother so that the removal of wax after play is less painful.
Space Prep
You can also prepare the space by protecting your furnishings by coating with a layer of plastic and creating a non-slip environment for the floor.

Paraffin wax is a common starter wax. Some dilute it with mineral oil to soften it further and allow its melting point to drop. Stearine hardens the wax and increases the melting point, meaning that it melts at a higher temperature.
Temps
Other ways to vary the temperature involve how close the flame is to your skin. The further away the wax is from your body, the cooler it becomes when it actually makes contact with your skin. The opposite is true when the candle is closer to your body. You may want to start off further so you can take notes about your own heat tolerance. Another great area to test temperatures is the inside of your forearm. If in doubt, that area will definitely tell you whether the temperature is too hot or too cold. Better erring to the cold side when first beginning by being careful in not burning yourself!
Other
Other safety precautions include scents. Some people may be allergic to scented candles or even the paraffin itself! Know as much as you can before you play!
