Yoni massage or yonic massage is a type of Tantric massage that primarily focuses on the vulva and vagina, in the same way that Lingam massage focuses on the male genitalia. The massage is viewed as therapeutic and is sometimes introduced as a method of relieving tension of the vagina. It has been claimed by practitioners to be helpful to achieve fertilisation, although there is no scientific support for this position.
