Flame Ⅳ has three motors, each with its own job. The tip vibrates deeper inside; the middle of the shaft taps rather than buzzes, pressing into the front wall where the G-spot area sits and releasing, like a finger making a come-here motion; the external pad vibrates on the clitoris. The tapping comes and goes rather than holding steady.
Begin with the external pad alone until you are aroused and wet, then insert with lube. Turn all three on low and notice which one your body answers; raise that one and leave the others quiet. Worn in your underwear, the remote version lets a partner set the pace. It is waterproof; add lube in the bath.
