When you are alone with yourself you can try learning to react to the normal stimulation again. Leave the vibe in the drawer and try touching your sensitive points as slight as possible. Continue as far as you can come. Probably you will see that this works surprisingly well.
I had a time I masturbated so hard that I got an inflammation on my cock´s tip. That was because the normal stimulation was not enough. The itching forced me to do it very carefully, and, surprise, surprise, it worked.
