My favorite is oil based lube because you can use it in the shower and it doesn't get sticky as it dries, but, it's more of a pain to Clean up. I've actually just tried a pill of lube you insert into your vagina about a half hr before sex....Dan brilliant! It's a lot of lube but we work through it pretty quickly. Lol. It's just nice not to have to stop and grab the bottle every ten minutes.
