The anal area of the body is not naturally lubricated. The use of a personal lubricant is therefore a must for pleasurable anal sex. This is the only way of compensating for the lack of natural lubrication in this area. The pjur anal lube products also contain certain additives such as jojoba and hyaluron to make anal sex even more enjoyable.
They make a big difference and are highly recommended for both partners to enjoy it more.
