Lubricant (also known as “lube” or “personal lubricant”) aids in sexual activities that test the limits of your body, as well as supplements personal moisture when your desire outlasts your body. Lube is also known to increase sensitivity. It is safe to use externally as well as internally. Only water-based lube should be used in combination with a sex toy or condom, as non-water-based lubricants are destructive to such materials. Oil should be used externally and never on toys or with condoms. It can be scented or flavored, and is a great accessory to keep in your bedside drawer for relaxing, sensual massages or foreplay.
