“Perhaps it is because your bladder lays against your G spot and when the bladder is full it pushes the G spot further into the vaginal canal causing it to recieve greater stimulation.
You can get a minor implant between the urinary bladder and the outer wall of the vagina /cervix to place the G spot into position for Grafenberg orgasms from sexual stimulation.”
