It's a pity there is no "other" option. Frankly, I'm not the biggest vibration fan - most of the times I'm way too sensitive and almost any kind of vibration makes me feel sore. However, clitoral stimulators (not strictly vibrators, since they have many other functions/features) are certainly up my alley.

A good vibrator is flexible, made of soft but firm material, has multiple speeds, with clit stimulation.
