I'm looking for a product that I can use for massage and for sexual lubrication. What are my choices?

Your best choice would be a silicone lubricant. Water-based lubricants are safe and wonderful to use during penetration, but dry out too quickly to be used for massage. Silicone lubricants, however, never soak into the skin, so they make for a wonderfully slippery massage, and are also safe to use on genitals. Just be sure to wash off with soap and water afteward to take away the slippery feeling.
