ummm, just to clarify... The cervix dilates, not the vaginal opening. Those muscles are designed to stretch to YES!, fit a baby's head through. And no, it does not mean that we are grand canyon like, they do go back, especially with the proper excercise...


Onto the original question at hand. Only the first part of the vaginal opening is extra sensitive to feel, there are lots of nerves bundled up in that area. The rest is less sensitive, but varies from woman to woman. Penetration, for me can only be felt at the opening and wherever it is reaching, not much in between, so different posistions allow the penis to hit different areas, and some are more sensitive than others. Just explore and experiment and you will find the ones that feel best
