Anal vibrators differ from other types of vibrators in that they have a flared base to prevent possible loss in the rectum.[1] The average size of an anal vibrator is smaller than vibrators intended for vaginal penetration and may vary from 4-6 inches long and about 1 inch wide. As well as other vibrators designed for external and internal stimulation, anal vibrators are usually battery operated: the batteries may be inside the unit or connected by wire to a power pack.
Unlike anal dildos, such as butt plugs, anal probes and anal beads, vibrating anal toys may produce various stimulating effects: rotating, vibrating or pulsating, and can have different speed or vibration levels to regulate and adjust the vibrator to various sensations.
Anal probes, with vibrating effect are smaller than usual butt plugs–about the size of a finger, which make them a very helpful anal toy for beginners. Anal probe vibrators may be narrower because their main function is to slide and vibrate.
Vibrating butt plugs are made to stay inside the anus to create fullness and vibrating stimulation at the same time. Their advantage is that they can be simply left in for anal stimulation during solo or partners' sex to receive multiple enhancements.
Vibrating beads and balls are a number of small beads or balls joined together through a long retrievable cord to a power control. They may not only be inserted and pulled out but also vibrate at different speeds.
P-spot vibrators are made in such a shape with curved heads that these facilitate the stimulation of the prostate.
Anal vibrator shapes can vary depending on the brand and buyer's preference.[2] Among the most common ones you can buy if they are phallic shaped (similar to a dildo), elongated or curved shape. length rarely exceeds 15 centimeters with a diameter of no more than 11 centimeters. They usually have an internal motor with a matching battery, a bluetooth interface to control the device with a smartphone or special remote control, and a charging plug.[3]
They can usually generate different types of vibration, and in products marketed primarily for prostate stimulation, the internal motors may be individually controlled or the shape may be articulated.[4] [5]
Materials vary by brand, but among the most commonly used is silicon to facilitate disinfection (using sodium hypochlorite, alcohol).[6] [7] [8]
If they are not used properly, especially if they are very small or not optimized for proper use, they can present a problem of medical and surgical interest because, once lost in the rectum, self-extraction is unlikely to be possible.[9]
Some clinical and academic studies have shown that the use of vibration-induced prostate stimulation can help in the sexual rehabilitation of patients who have survived forms of prostate cancer.[10] [11]
