My Man and I have found the Sliquid H2O Ride
the best lubricant we've ever used. It's water based, but lasts a long time. it's safe for toys of all materials, for vaginal use and also lasts long enough and is thick enough for anal sex and anal play. (From what I have read, it's thicker then the Sliquid H2O, and lasts longer.)
In our opinion, it's the best lube on the market!
