I used this for solo play tandem with some paraffin candles to experiment with how my body might enjoy wax. I experimented on both sensitive areas like my chest and more neutral areas like my legs. Due to the shape of the candle the head of the dick created a really nice well as the candle melted. That being said the burn temp for this candle is super hot, I found even when pouring from the maximum distance I could manage as a solo player I still was on the verge on being burned. This might be nice for people with a higher pain tolerance but by the end of the experience I found myself not using it entirely.
