I prefer water-based all the time. It doesn't matter if it's anal/vaginal penetration, or for putting in my menstrual cup. I have mostly silicone toys, so silicone-based lubes are a no-no. Plus, I don't like having to worry about staining or trying to clean the stuff up. I have one bottle of it, and basically just use it to oil the door hinges and whatnot.

Same for me. Water based is all I use. I'm super sensitive to some ingredients so I go with water-based hypoallergenic lubes.

I use water based lube for everything except anal sex. Then I'll grab the silicone.

we use mostly water based lubes. Easier to clean up. feels better for us. And we dont have sex in water very often.
