Just in case you needed another reason to adore the fully stocked PinkCherry Kegel Training System, here's one: regular kegel practice can actually increase the intensity of your orgasms. How's that for some workout motivation!Kegel weights (sometimes known as ben-wa balls) have been around for centuries, but these days kegel exercise is a well known practice in gynecological/obstetric circles. Kegels - the act of consciously and repeatedly flexing the pelvic floor muscles - can help tighten up the pelvic floor. A tighter pelvic floor leads to improved inner snugness, better control of continence after childbirth or surgery and an overall happier vagina. Oh, and stronger orgasms, as we mentioned above.In super silky silicone, these teardrop shaped weights feature an ultra smooth surface and long, flexible retrieval cords. There are five weights to choose from, each providing a great-feeling object for your pelvic muscles to grip during your kegel exercises.The lightest pale pink version weighs in at 1.4oz/40g, and is a perfect starting point to kegel practice. It'll provide the least resistance and require the least amount of 'flex' to keep it in place. If you find that one breeze, you can move on to the rosy pink berry at 2.1oz/60g, the darker pink at 2.8oz/80g and on through the heavier versions at 3.5oz/00g, 3.75oz/105g and 4.2oz/120g.  Pro tip: use a little water based lube for easy, comfortable insertion.In highest quality silicone, the PinkCherry Kegel Training System is hypoallergenic, body safe, and a breeze to clean and maintain. Before and after use, wash your kegel weights with lots of warm soapy water, or use a favorite toy care fluid/foam. This PinkCherry pleasure offering is compatible with any favorite water based lubricant, but please keep it away from silicone lubes and other silicone toys*Balls measure about 7"/18cm in total length and they're about 2.5" (6.4cm) insertable. Each ball is approximately 1.25" (3.8cm) in diameter
