I definitely prefer silicone lube and use Bodyfluid
I do like Liquid Silk
as well—which is classified as a water-based lube, but comes with a touch of silicone.
I also love Organic Love Balm
which is a coconut-oil based, all natural lube. I actually use it as skin softener, rather than lube, but it's a great choice for anybody looking for an organic product, a product safe for latex (coconut oil instead of petroleum oil is safe for condom use) and who prefers the "oil" consistency.
