No, you would be misinformed there; ballooning is primarily anti-BC clenching, and while you can still balloon and kegel, it won’t be as effective.
Many times while in the middle of a ballooning session, I’ve found it near impossible to not kegel, and when I do, I can feel a rush of blood exit the penis - the same rush that when it comes in, signals proper ballooning.
Ballooning is a combination of mechanical manipulation and energy direction, whereas edging is simply withholding from cresting over into ejaculation.
I started out kegelling during ballooning, however I don’t kegel, anal breathing is enough to keeps penis pumped. By definition edging is basically base stroking. Ballooning is more sweet spot rubbing and glans rubbing. And not ejaculting at all. Of course I often fail at this. I find after a few days of not ejaculating that the physical energy level is to m uch to handle so I release that energy by ejaculating. But I hold on to enough of it to maintain normal energy levels. If I’m going to need more energy I wit hold for a few days from ejaculating.
Speak softly carry a big dick, I'm mean stick!
