The Butter Personal Massager is an external vibe designed to stimulate the perineum. Enhanced pleasure is within reach—hidden in your perineum—otherwise known as the gooch or the sandbar. The Butter Personal Massager is a waterproof, ultra-quiet, body-safe silicone device. That's right—no insertion is required to experience the goods. The Personal Massager is also great for any erogenous zone. The Personal Massager is fully waterproof. Shower time, jacuzzi time, steam time, and the like are all fair game.
