Yes, water based only
Zumio should only be used with water-based lubricants and should not be used with silicon-based lubricants. Zumio can be used comfortably without lubrication as well. You may prefer to use a small amount of water based lubrication to help reduce the intensity in the first few seconds as the tip and skin connect. If you prefer not to use lubricants, simply apply a small amount of natural wetness from the mouth or vagina to the Zumio tip and repeat as necessary.
