And, compared to more traditional direct-contact clitoral vibes that rely on rumbly (and sometimes too powerful) motors, suction vibrators operate with a little more nuance. The air surrounds and pulls the clitoris toward the vibe’s open mouth, attempting to evoke the sensation of being sucked (or replicating the feel of oral sex). All of this can create an orgasm so incredible that one blissed-out reviewer of a suction vibrator described it as “having their soul sucked out of their vagina.”
