interesting topic..
not for everyone,
there are special candles available, where the wax does NOT burn at such high temp that regular candles, try those first.
Drip candle wax into palm of the hand of the person who is craving the pleasure, IF too hot for them to be happy with DO NOT proceed anywhere else.
it is really meant to heighten pleasure and awareness, in the similar, but opposite way to ICE. once the candle is producing liquid wax it can be used in senstive areas.. such as inner thigh, to get the tingle going..
this is not my thing, but have had it done... may have been too tense to enjoy..
different levels, as it can go all way! EXTREME... clit and penis... and tongue... I can't see the thrill in that, but hey... it is a pleasure / pain thing, and testing sensations to extremes... ICE / WAX...
