I had a great chat with Kiana from The Tulip we chat all about the Yoni Egg.
Here is a little more info about it.
Please do let me know if you have tried it and what is your take on them.
Yoni eggs are small shaped crystal eggs. Yoni eggs are used for pelvic floor exercises. The different crystals have their own story and abilities, yoni eggs have been used by women over thousands of years. This is a great way to access your own sexual power. By using yoni eggs, you will improve your sexual sensations, tighten the vaginal wall and helps you experience more intense orgasms. Kegel exercise is also a good exercise to strengthen the core which gives a flatter and stronger stomach.
We recommend large drilled eggs for new beginners or if you have given birth.
For more advance and experience users that wanting to challenge their exercises, we recommend the small yoni egg.
