Water-based personal lubricants are a popular and widely used option made primarily from water and other ingredients like glycerin. They are known for being body-safe, non-staining, and easy to clean up. Their formula is compatible with all condom types and most sex toys, making them a versatile choice for nearly any sexual activity. They provide a smooth, natural-feeling glide but may require reapplication during longer sessions as they can absorb into the skin or dry out.
