Yoni is the name of the female genital in tantra
It’s more a very slow and gentle touches, rather than massage of the muscles. A touch can heal blockages, orgasm problems, it helps you to connect with your body on a deeper level and to connect with your joy.
During the massage, the genitals are being touched too. I do the massage either lying on the ground, on tatami, or on a massage table, and using hot organic coconut oil. It will be warm in the room, during the massage the guest and I are both naked, but there’s no mutual touching, the guest only receives the gentle touches.
