The vagina isn't supposed to be dry and douching should be limited to what the doctor requests. If you are using water based jelly, it should drip out in a few minutes. I tend to dilate and then do my normal morning getting ready routine which includes my shower. By the time I am done with my shower, everything has dripped out and I am good for the day. As you are still close to surgery, keep a good supply of feminine pads and change them regularly.
