Water-based and as healthy as possible. I like just having one lube, and I keep silicone as my squishy toy material. So I'm limited to water-based by that.

water based. We have tried some silicone lubes, and have not liked them as well as the water based ones. She does not like any lube, water based because they get sticky, and silicone because they dont feel real. We use water based when she is not wet enough for sex.

my current fave is sassy booty by sliquids. Its water based, body safe and thick.

I prefer water based, as well, simply because I can't remember what all my toys are made of and I don't want to fiddle around with different lubes that are safe for some and unsafe for others.
