I've tried the Sliquid Organics Silk and LOVED it! It closely mimics my body's natural moisture, has little taste, and doesn't get sticky. It's perfect for me because I don't need a lot of additional moisture for penetration, and if oral sex ends up happening after penetration, the taste is negligible.
However, it is
a water-based lubricant and will dry out before a silicone or oil-based one will. Spit or a spray of water from a bottle will reconstitute it quickly and easily. Also, it's easy to wash off and doesn't stain if you get it on your bedsheets!
