How many of you have tried it yourself or had your significant other use it on you until you had an orgasm?
You should seriously consider investing in something like the Eroscillator or the Smart Wand by Lelo. The Hitachi is too intense for clitoral stimulation. At first I'm sure it felt great but it will soon counteract itself. The vibration is so intense that it will cause desensitization through nerve damage and micro-tears. You can rehabilitate the area using toys with medical grade silicone... that is the exact purpose for the Eroscillator. Please do not ever use the Hitachi for anything other than muscle relief... on the low setting.
I enjoy penile stimulation with a strong vibrator. Have never tried a Hitachi wand, but have used similar devices, with mixed results. Normally, it takes longer to reach a point where I can orgasm, but the resulting climax is usually more intense.
