Indeed, we do! We, being the Brooklyn organic-local-hippies that we are, tend to like to use things with the fewest unpronounceable ingredients possible. We enjoyed Astroglide's glycerin and paraben-free version for quite a while, until we graduated to Sliquid's H2O. It's water-based, fragrance-free, basically the next best thing to pussy juice.
Most often, when we're using lube, it's for anal sex. In that case, we cannot say enough good things about Maximus. It lasts an extra long time and doesn't get as sticky as some others.
