Our favorite lube for regular sex is O'My. It's also our favorite for masturbating (hers and mine). It's just so soft and smooth and doesn't dry out or get sticky and you don't have to use a ton. We've tried allll kinds of lube and we agree that it is by far the best.
On the topic of funny lube bottle stories, the first time Sage and I ever had anyone over to our apartment we had to make kind of a mad dash to clean up all of our sex stuff... We got all of the big things but missed the tiny sample bottle of Doc Johnson's Anal Lube that came with a buttplug we had just bought. It was just right out on the counter, and of course it only took our friend a few minutes to see it. We were pretty well mortified until he confessed that he and his girlfriend were into that sort of thing as well.
