Kegel balls
A Kegel ball is a sex toy that is a small spherical object usually made of soft plastic or metal. It is used to provide stimulation and pleasure during sex and can help women achieve orgasm. A Kegel ball is used by inserting it into the vagina and using the force of muscle contractions to control its movement. This practice can not only provide pleasure, but also exercise women's vaginal muscles and enhance the quality of sexual life.
