The perineum (area behind the scrotum before the anus) can be powerfully arousing when sexually stimulated. The Root Rocker ER was designed to vibrate both the legs of the cis-male clitoris and the perineum, and sends powerful arousal through the skin to the pelvic plexus. The erection ring is much more flexible than the Black Swallowtail, but the powerful, rechargable vibration is just as strong, but turned to allow it to be nestled back behind the scrotum. Ten mode, throbby vibrations with a rechargeable removable vibrator.
Oh, and there's also a remote control ring. Hmm, who wears the ring? Engagement has never been so arousing.
