I had this done to my cock; but my cock was put in a cardboard tube; the candle was melted in a pot on the stove and the wax poured into the tube and round my cock. Waited till the wax cooled a bit before pouring it over my cock (ie. just before it solidified again). Removed the cardboard after the wax set and there it was - a candle cock. It frightened me as the wick burnt down but I enjoyed the experience.
