Here's the skinny on diff types of lubricant - some are better than others!

* Silicone-based:  long lasting, waterproof but can break down other silicone products like sex toys.

* Petroleum-based:  (like petroleum jelly, Vaseline)  irritates vagina, and will break down latex very quickly

* Oil-based:  (vegetable oil, butter) safe for vagina, but also breaks down latex

* Water-based:  (water, glycerin, paraben)  safe for vagina, safe for use with latex and latex products.  Dries out the quickest, but can be rehydrated using some water or more lubricant.
