Most of the battery operated vibrators just don't cut it when it comes to anal. I have to side with many of my lesbian friends...the Whal vibrator with attachments from Good Vibrations is the tops!
It plugs in the wall, so no batteries to run down, it has anal/vaginal probes, and the sensations it delivers are INTENSE! Because this is a "coil" vibrator instead of a motorized vibrator it runs at a higher freequency, and once you've tried it, there is no going back.
I can attest to this from personal experience and from testimony of partners.
