Water based sex lubricants get absorbed into the skin when applied, evaporate and eventually dry out, thereby leaving behind a residue. If you want to reactivate the effect of water based sex lubricants, you either have to apply them again or apply water or saliva.
Oil based lubricants can damage the materials of many toys. Silicone lubricants should not be used with toys constructed out of silicone. Only water based lubricants can be universally used. This makes them more versatile for individuals and couples who own multiple toys.
Water based sex lubricants are not recommended for use during sexual activities that happen in water like swimming pool, Jacuzzi, shower or bath tub as they easily dissolve in water. Also, water based sex lubricants are not thick enough for anal intercourse or anal play with sex toys comfortable. Water based lubricants can easily be washed with water and do not leave stains, unlike silicone based lubricants.
Water lubes are highly recommended to use with condoms for safe sex as they do not deteriorate the condoms, unlike oil based lubricants. As water based sex lubricants contain water as their main ingredient, they are easy to clean using plain water and little soap. This makes washing your hands, bathing and cleaning sex toys simple and convenient.
