If you have a sensitive clit, do NOT put a strong vibrator directly on it. Unfortunately, I used a a strong vibrator on my favorite super-sensitive spot. I had an abrupt strong orgasm after a few seconds before I even had a chance to get excited, but I think the vibrator ripped a surface nerve because that spot -- which had been a favorite for years -- became numb and that delicious sensitivity never returned. I can barely feel anything there ever since that day. Very sad.
