A representation of the vulva which symbolizes the goddess Shakti is a type o Tantric full-body massage. 

Contrary to some beliefs, the purpose of Yoni massage is not solely to achieve orgasm, although it commonly occurs during Yoni massage. This is presumably because of the higher rate of achieved orgasm during masturbation, compared to sexual intercourse. Due to the stimulation of the vulva, clitoris, g-spot and if desired also the anus build-up, and combined and constant stimulation to the erogenous zones during the massage, achieving orgasm via Yoni massage is probable.

HOW DOES IT WORK ?

You lie face down on your tummy and I massage your whole body using warm aromatherapy oils starting from the shoulders. After the massage you turn around, lying on your back, and I then massage your Yin side. The massage continues, slowly transforming from whole body massage, to breast massage, to stimulation of the vulva, and finally deep vaginal stimulation. Massage oil, like in many other forms of massage, is not only used, but is also an essential part of the massage, to provide a sufficient amount of lubrication.
