Silicone 

Water based lubes are too limited for some with sexual appetites for long, intimate nights. Silicone is the longest-lasting lube on the market. A silicone lube is also thicker than a water-based lube. It allows you to enjoy your most erotic moments longer, without interruptions to reapply. Silicone lube can be harder to clean and is not compatible with silicon sex toys. However, silicone lubricants also work in the water, which means you can have intense lubrication in all kinds of situations, like the shower, hot tub, or pool. Try silicon lube to see how long you can last.
