The clitoris can lead to a great orgasm — or not. Overstimulating causes shutdown; too little (or on the wrong fraction of a centimeter) is a waste of time. As someone who knows my way around a great clitoral orgasm, I was curious about Rush, a sex toy that relies on air puffs instead of direct contact. With subtle sensations and modes that feel weirdly like a human oral sex champ, it took me down some surprising new paths to the finish line.
