And if you've found yourself specifically comparing water-based vs. silicone lube, good news: The difference is actually pretty simple. That staying power can make silicone lube harder to wash off, and it isn't always compatible with silicone sex toys. Some silicone lubes can damage silicone toys over time, so both experts recommend checking the toy manufacturer's instructions—and sticking with water-based lube when you're unsure. That doesn't mean silicone lube and silicone toys can never coexist, though. Water-based lube is generally the more versatile option, while silicone lube lasts longer, but the “better” lube is whichever one makes the most sense for what you're doing.
