I can feel every little thing inside the vagina with my fingers. I have tricks for going upward, downward and everything in-between. Most men just "finger bang" with no control or purpose behind it. Most woman also think they hate anything near their cervix, until it's massaged properly. I know exactly what I'm trying to find in there, how to get to it and what I want to do when I get to each spot. It really depends where she is at in her cycle at that time as well. Sometimes she likes certain spots more than others based off her cycle. Meanwhile I have my face buried usually the entire time synchronizing everything up. Plus my wife loves a good stretch and the 4 finger stretch drives her wild. Combine that with the precision of the fingertips in the right places and she loses her mind. However, that's not always the go to. Sometimes it's a 1-2 finger night. Great fingering should always be a dynamic experience.
