Quoting Raptor Jesus:" This fascinates me. Exactly what is the benefit of using these things and developing your muscles down ... [snip!] ... jam your whole damn fist up there or what? I just can't imagine losing a golf ball-sized object in my twat... How weird, lol."
Well, they're very helpful in keeping your PC muscles tight and strong. It actually CAN make a difference even if you haven't had children- It doesn't hurt to do a little maintenance. It can keep your muscle control tighter which means bladder control can also be better as you get older. As we get older, sometimes sneezing or coughing can produce a little leak- It happens more often than we think, so these balls can help prevent that in the future.
They can't get lost inside you, so it is not an emergency if they get a little stuck lol They make Smartballs with a string connecting the balls (I have them, but I took the string off, it was too rough and irritated me.) Once you are strong enough, you can just push them out. Within the week I've been able to push them out on my own without my hands- so I don't have to worry about them being stuck. My BF told me he noticed a BIG difference in my muscle control, he was actually a little sore from how much tighter things were lol. And that is only in a week of daily wearing.
SO I think they can help in a few different ways....Doesn't hurt to try
