Since your natural wetness can decrease due to a variety of things (stress, medication and birth-control pills), adding lube helps ease penetration making sex & masturbation much more pleasurable and not painful. But using lubricant can be effective even when you don't have vaginal dryness. It adds sensation and also makes condoms more reliable. Lubes come in a variety of flavors and types. Anal Lubes are used for Anal Play. These lubes are thicker than average for safer more comfortable anal sex. Some contain Benzocaine to numb the anal region and ease pain.
