If your pussy feels numb...
It can be helpful to put a finger inside of your pussy, instead of your egg, to get a sense of the muscles moving.
It takes some time to develop the ability to squeeze this way… don’t worry too much about doing it right away – just spending this time focusing on your vagina and encouraging a mind-body connection is very helpful.
Over time you’ll develop the muscle control to be able to differentiate and feel more, and it’s fine if all the muscles get involved at first… over time they will get more specific.
