Lube in the eye?
We get our lube from one of the local sex stores. It's, umm... well, let me go look.
Okay, it's called "system jo h2o" and it cost us $20. It's water-based, but feels like it's silicone based. Oh, and it's approved by the fda - yay. It's good stuff. I won't post the url obviously, but you can google it and take a looksie.
