Eva ($135) is a staple of the couple's toy revolution. So many couple's toys promise easy placement but tend to have slippage. You won't find this with Eva. The tiny vibe has wing-like extensions that hook under the labia to keep it in place during penetrative sex. The vibrator itself sits atop the clitoris, offering the much-needed attention women need to this sensitive area. It's a hands-free way to close the orgasm gap for more satisfying sexual experiences.
