The first time I wore Loa balls and walked around I could really feel the inner balls moving. This is in contrast to Eclipse balls that required me to jump up and down before I could feel movement.
The second time, however, I only felt a very occasional movement. With repeated trials, I've observed that its when it feels like I have trouble pushing them in all the way - when they are quite low - that I can detect the movement of the balls. When I'm perhaps more aroused and can insert them fully without struggle, I almost need to do cartwheels to feel the inner balls move.
I've tried doing kegel exercises with Loa balls in place. It didn't feel any different and certainly wasn't an improvement over kegeling without them.
A
recent study measured the improvement in pelvic floor muscle strength in women who performed kegel exercises either with or without a device that is a weighted sphere of about one inch diameter. Over sixteen weeks both groups improved pelvic floor strength but the women who kegeled with a sphere inside didn't improve more than those who kegeled using no device. Loa balls aren't one inch spheres but my feeling is that the same results would be seen if the study used Loa balls instead.
However, maybe if they completely fill you when they're inserted there would be some benefit. And certainly it can be fun and arousing to have them inside. The back of the package calls them "the perfect instrument for erotic foreplay." This is their true purpose. Arousal.
I didn't personally find them to be arousing. Once they're inside, the thick retrieval cord is outside. Its so thick that you will be continually aware of it. If you wore something like leggings or just underwear while Loa balls are inside you, you would see the thick loop bulging through.
It feels like it holds my inner labia open and props the opening of my vagina open too. A side effect of this is that vaginal fluids leak onto my panties making them quite wet. Its like I'm twenty again! Honestly dripping like this just doesn't happen any more at my age. Prepare for panties that are substantially wetter than usual as you wear your Loa balls.
Aside from arousal, their other purpose could be to remind you to do your kegel exercises. Its better to do concentrated, focused kegels where you're not walking, reading or otherwise mentally or physically engaged, but if you end up doing more squeezes as a result of wearing them, even if they're just quick little squeezes, that's better than nothing.
Thanks for the review!
