The very first essential to sensuality is lubrication. Hands down, the smoother things move the better. Even for those of you who don't want to experiment with anything else, lube may be your best friend. One great thing about it is variety. Lube comes in different scents, flavors, textures, warming, cooling, or plain; there is definitely room to try others if you dislike one. Personal recommendation: Jo. If you have no partner and are doing only solo sessions, lube will increase your pleasure, so if you are having orgasms there is no excuse.
