Water-Based are the most popular type of personal lubricants. The most popular personal lubricants are water-based, such as Astroglide, KY-Jelly, Slippery Stuff, Liquid Silk, ID Lube, Astrogel, Maimus and Probe.
Water-based lubricants typically do not stain. They do not irritate the skin directly (however, see disadvantages below regarding yeast or bacteria which may lead to irritation). Water-based lubricants are safe to digest, and they are easy to wash because they are water-soluble. Water-based lubes are also safe to use with sex toys.
Water based lubricants contain water which evaporates — in the case of some water-based lubes, very quickly. As the water evaporates, the lubricant becomes less like lubricant and more like glue. A simple adding of water to the mixture is enough to get the lube feeling wet again, but doing this multiple times during a long sexual encounter can be distracting. Another disadvantage is that water-based lubricant is made of materials which can feed bacteria or a yeast infection. A thorough cleaning and vaginal douche should be used immediately after using water-based lubricant if yeast infection has been a problem.
