Anal Balls are the perfect sex toy to begin with, for anal stimulation.
The point of Anal Balls is simple: pleasure! The nerves at the entrance of the anus are incredibly sensitive and when stimulated, you can experience pleasure. If you have a vulva, you can actually stimulate the vaginal canal through the backspace [that means butthole, FYI] and create a sensation of fullness. And if you have a penis, Anal Balls can be rubbed on the prostate, which is colloquially called 'the male G-spot'. The best part of Anal Balls is that they can enhance pleasure in almost any sex act for every body and partner combination.
