The Arcwave Ion is unique from other masturbators because it provides stimulation that targets the shaft's underside and frenulum. The frenulum is one of the penises' most sensitive erogenous zones that can deliver knee-buckling orgasms. In fact, some sex educators and texts even categorize frenulum-based orgasms as a different type of orgasm, similar to clitoral vs. vaginal orgasms. Unlike other masturbators, you don't penetrate or 'thrust' the Arcwave, instead the penis is inserted and you allow the suction to do its thing. The Airpulse technology adds suction and pulses against the back head of the penis, which edges you towards an intense orgasm
The sleeve features unscrewable caps on both ends, which can be used to create a suction when one end is capped. The sleeve's gel material is ribbed on the inside and feels high-tech, like a cyborg vagina designed to reach every nerve-ending; the plastic cylinder is made of robust plastic and is comfortable to grip.
