You'll Never Know It Isn't Boy Butter is a water-based gel lubricant with added Vitamin E and Shea Butter. The result is a creamy textured waster-based lubricant that subverts the evaporation process, which avoids any need for reapplication of lubricant or addition of water to recharge it. It will keep going and going very much like oil based product and eventually absorbs into the skin like a lotion.
