Yoni: Yoni (Sanskrit: yoni, literally "vagina" or "womb") is the symbol of the Goddess (Shakti orDevi), the Hindu Divine Mother. Within Shaivism, the sect dedicated to the god Shiva, the yoni symbolizes his consort. The male counterpart of the yoni is Shiva’s lingam. Their union represents the eternal process of creation and regeneration. Since the late 19th century, some have interpreted the yoni and the lingam as aniconic representations of the vulva and a phallus respectively
Kegels: Kegels can be done without a yoni egg and you will still get all the physical benefits.
"Kegel exercises are simple clench-and-release exercises that you can do to make the muscles of your pelvic floor stronger. Your pelvis is the area between your hips that holds your reproductive organs. Thepelvic floor is really a series of muscles and tissues that forms a sling, or hammock, at the bottom of your pelvis. This sling holds your organs in place.
