Water-based personal lubricants are the most commonly used sex lubes and the gentlest type of lubrication for sensitive tissues. They dry out during use relatively quickly, but most people find the techniques used for reapplication a definite perk. The easiest way of reapplication is to add a small amount of water to the dried lubricant. Some of the newest water-based sex lubes have natural skin moisturizers like Carrageenan and Aloe added to make them feel silkier. One drawback: They wash off in water, so they’re not great for sex in the hot tub or any other water locations.
