When choosing a clit vibrator, there are three things to consider:

1. The size of the toy. You should choose a toy that's proportionate to your body and the amount of time you'll have to use it.

2. The material of the toy. This will depend on your personal preferences, but some materials are more hygienic than others.

3. How much power the toy has (as well as whether or not it has variable speeds). The stronger the vibrations are, the better!
