Vibrating Penis Rings are a great way to add erection performance for the wearer, but also offer enhanced stimulation for your or your lover using vibration – usually top mounted for clitoral stimulation, however many also have a second motor for scrotum or perineum stimulation for the wearer. Most use a simple battery power vibrating bullet which is removable, however many newer models offer a rechargeable motor which may be integrated and not removable.
