Lingam figure candles are a traditional candle used in folk magic and witchcraft for working with sexuality, seduction, and the current of mascululine energy. The red figure candles are usually worked in spells for love spells, passion, and desire. They can also be used to channel masculine empowerment.
Black lingam candles are used in workings to curse a person's manhood, anointing it in Crossing Oil, and burning it alongside Black Arts Self-Igniting Incense Powder to make one impotent. Another working is to anoint a black penis candle in Crossing Oil, and dressing it in pepper. With several pins, pin the manhood and then bury this in a graveyard. 
Each magically-crafted candle is hand-poured and rooted in traditional designs, and used to amplify intent and command results in your spellwork
