Kegel exercisers (kegel balls) , which fall under the category of love eggs, not only serve as a means of teasing, but also utilize the principle of gravity. When these balls are inserted into the body, the vaginal muscles unconsciously tighten and contract under the influence of gravity, resulting in an exercise effect and helping to restore vaginal tightness. For those with clitoral sensitivity, using these balls externally can provide pleasurable sensations. After stimulating the clitoris externally for a while, it is recommended to slowly insert the balls during increased arousal to ensure a smooth and pleasurable experience.
