When my friend did hers she said her doctor told her erectile tissue takes longer to heal, and that's why some seem to take so long. She also said that at first she wanted to walk around holding them all the time, to protect them from any accidental bumps or brushes. It's been a couple years now and she says they are still much more sensitive than before she had them done, but not so bad that any movement tiggers them. I was thinking of doing it since mine are not that sensitive, but I'm afraid I would get the raw end of the deal and end up with NO sensitivity.
