Hi Julie,
I felt pretty numb down that way for the longest time. Still do to some degree... but try the magic wand test. No joke, pick up a Hitachi magic wand (google it, they are legendary), and just play with it for awhile. I became suddenly aware, that there are nerves in that place, they just need a little convincing. More come on line every week, 11 months post op. This past weekend, a friend "woke" some more up for me in a place I never had feeling before. Don't despair!
Good luck, Have Fun.
