Sex is great and it is even better with the assistance of lubrication. Vaginas create their own lubrication, but sometimes it just isn't enough. Anal sex, onthe other hand, will require the use of lubrication since the anus does not produce its own. Lubrication come in different materials, scents, and with agents that increase sensitivity in your private parts. You can pump that hole with maximum vigor using a slippery wad of lube on your pecker.
