I prefer water based because it feels better .. here are more reasons water based is better:
Easy to wash off: Water-based lubricants leave minimal residue and are easy to clean up.
Compatible with latex condoms: Water-based lubricants are compatible with latex condoms.
Mimic natural body fluids: Water-based lubricants mimic the body's natural fluids, such as saliva, mucus, and vaginal discharge. This makes them non-irritating and less likely to cause reactions.
Cleaner than oil-based lubricants: Water-based lubricants are cleaner than oil-based lubricants, which can stain sheets and clothing.
