A lot of candles that I see marketed as "sensual candles" usually have ylang-ylang in them - mixed with a combination of one or more of the following: jasmine, sandalwood, rose, patchouli.
I personally like to use some of the Slatkin Kabbalah candles. A few of my favorites are:
- Sexual Energy - Amyris, Saffron, Red Plum, Red Pepper mixed with Rose, Clove and Red Leather
- Passion - Red Jasmine, Apple, Mahogany with Patchouli and Heart of Patchouli
- Evil Eye - Italian Bergamot, Nutmeg, Wild Berries, Chamomile, Cedar, Honey with Myrrh and Vetiver (I know the name does not sound very sexy but I just LOVE this scent in the bedroom)
