What is the safest way to use a vibrator?

We got our oldest a vibrator on the recommendation of my wife's OB/GYN. She had given herself several infections from not cleaning whatever she was using so the OB said to get her one and teach her how to keep it clean. We ended up getting her a simple 4 inch waterproof one with some sanitizer and a bag to keep it in. She hasn't had an infection since. We didn't teach her how to use it; but did teach her how to keep it clean. Hopefully she will continue to take care of herself and stay out of boys beds for awhile.

Bullet vibrator. There are tons, as cheap as a couple bucks. It is for clitoral stimulation. I don't really think she would need a vibrator for internal use as her age. :) With all toys, you need to take proper care of it, which means washing it, they sell toy cleaners but you can also use soap and warm water.

Any of them that vibrates is good:))
