There are four types of personal lubricants: silicone-based, water-based, oil-based, and hybrids. Silicone-based lubes are usually thicker, silkier, and last longer, while water-based lubricants, as the name suggests, are mostly composed of H20, so they wash away easily and don't leave residue behind. Oil-based lubes, meanwhile, have the thickest viscosity, but don't last as long as the others. And hybrids? Those are a mix of silicone and water-based formulas that last longer than water-based lubes, but aren't as thick as the silicone variety.
