The Condom-Compatible, Vibrator-Compatible, Super Personal Lubricant. We like Astroglide for what it's not: it's colorless, odorless, flavorless and spermicide-free. Incredibly smooth and close to nature, space-age Astroglide goes a long way - you'll need no more than half a teaspoon to lubricate all your "moving parts." When it finally begins to dry, just a drop or two of water instantly restores lubricity.
