What springrain was describing about nerves is a process called desensitization and is documented in studies involving vibrating and heating sex toys. Nerve endings increase their tollerances over time. At first it was thought that excessive masterbation would cause desensitization, but that has been limited to just the excessive use of stimulating agents. The long fix would be to gradually lower the speed of the vibrator during each session so that you can ween yourself off of the excessive stimulation. The quick fix is to just give up all stimulation( sex, oral, masterbation, etc.) in the area for a period of days or weeks. Let everything heal to the point that any touch feels like the first time. That can be fun.... if you can manage to wait that long!!
