I love love love these Kegel Balls. They are weighty and are a larger size, so they are still easy to "grasp" with your PC muscles, but they provide a decent weight to work you out. The cord in the picture looks like it is fabric, but it is actually a stretchy and sterilizable silicone cord.
When I first started having sex, my orgasms were mild and hardly relieved the tension that I'd build up trying to reach my climax. I've used kegel balls for a few months, and I was able to move up from a lightweight set to this set, which is heavier. The weights inside roll around and create gentle sensations while I go about my day.
I don't typically wear these ones to work, like I did with the lighter set, because I end up getting VERY wet as I use them. The weight presses against my pelvic floor muscles, making them work out while I do whatever it is I'm doing. The balls just make me very aware of my vagina, and make me very aware that I'm not having sex! I don't have a problem with my sex drive, but I imagine that for a woman who finds herself having a hard time getting aroused, these would be a great item to wear when preparing for a romantic evening.
Using kegel balls (or orgasm balls) has helped me have better control of my pelvic muscles. Ladies with small bladders will understand the struggle of having to go to the bathroom RIGHT NOW HURRY OMG, but using these has helped me have better bladder control, too!
Now that my orgasm muscles are stronger, I can clench and unclench when I'm near orgasm to help push me over the edge. I can also actively clench and unclench as soon as my partner enters me, which, I've been told, is "hot as hell". Having stronger vaginal muscles helped me feel sexier, more confident in the bedroom, and even helped with bladder control. I would give these 10 stars if I could! If you want to tone your vaginal muscles, these are a great bet :)
