For some women, putting any personal-care product near their "personal chemistry set" is a game of chance, since most lubes, soaps and personal washes contain glycerin, which is similar enough to sugar to worsen existing feminine issues. Those users will love the hemp-based Natural Lubricant, which is glycerin-, paraben- and flavoring-free. It comes in a well-designed bottle featuring a lockable pump and a bottom-heavy shape that makes it stay put, even during one-handed use. Natural Lubricant has staying power, too: If the applied lube gets dry, simply add more water, and you're back in business. Available in 4- and 8-ounce bottles.
