Size and weight are things to consider. You can get large size and light weight to stay in or any variation. Your set are 58g and 4.25”circumference and the ones you are looking at are bigger at 5 and 200g weight.
Are you trying to exercise the muscle or just enjoy the pleasure as your choices can also change depending on the varied requirements of them.
Generally with kegel balls, larger and lighter is the way to start and work towards smaller and heavier.
However, there isn’t an exact science when it comes to size to weight ratio because it is very dependant on your anatomy.
Buying some that are larger and/or lighter might help, but what are you using them for? If it is mostly about pleasure/stimulation, then look at buying a different set. But if you are using them as kegel trainers, how hard are you squeezing? Pop them in and forgetting about them for ages isn’t really doing anything for your muscles as you need to squeeze and release around the balls for any noticeable improvement, and you only need to do this for a short time period.
You could say they are doing their job, by toning the muscles in that area, just try to keep them in by muscle contractions, my gf had the same problem when she tried them out.
Sorry I should have put in my original post. I’m only wanting for the pleasure aspect, not for exercising. Would you recommend to go larger but lighter? I guess it would be a bit of trial and error to find what works for me in this case?
Yes, larger and lighter would be the way to go. Think about how comfortable the current ones are to judge how much bigger to go, but I would probably focus a little more of larger rather than lighter (although don’t go dramatically heavier)
and they start to nearly come out.
