This explains the difference between Pleasure Air and regular vibration.
WOMANIZER™ products gently stimulate the clitoris without touching it, leading to a new kind of extraordinary orgasm – even if you’ve never experienced an orgasm before. The WOMANIZER™’s stimulator head encircles the clitoris and uses Pleasure Air™ Technology to gently pulse air in and out, stimulating nerve endings that wouldn’t otherwise be stimulated. It feels like sucking and massaging sensations but elevated to another level. Unlike vibrators that directly stimulate, Pleasure Air™ Technology doesn't cause desensitization or clitoral fatigue.
