[Dune] Could the Fremen have lube?

This is a dumb question, but it's one that me and a friend just got into a heated debate over. The Fremen have a culture of extreme moisture conservation, so a product like water-based lubricant would likely be seen as an extremely wasteful and stupid luxury. But could they use oil or silicone-based lubricants, or would they find some way to extract the moisture from these products from the tribe's sake? Are there any native plants or substances on Arrakis that could substitute personal lubricant?

I'm just worried about my gay Fremen homies.  


Edit: You guys are the best.

One thing to bear in mind is that moisture conservation is slightly relaxed within a sietch because the entire structure is designed for moisture retention/capture. So as long as you do it indoors, and don't do it excessively, you're probably OK with something water-based.
