You're missing out if you haven't experienced the pleasure provider by warming your Tenga masturbator before you use it. Tenga's official warmer works with its Cup masturbators, warming them all the way through from the entrance to the back. Simply slip the cup over the warmer and choose from the two heat settings: high and low/smart. The result is an experience that's more comfortable and realistic. The Tenga warmer is reusable and can be stored between uses.
