We have had it in the stats before for many years if it's not in this one (maybe in rainbow's thread) and all the jellies were the same as the overall success rates of the site, with the inverse (those who did not use it) being identical to the success rate with it, leading me to conclude it's not adding anything (but hey, also not swaying blue)
Most people DON'T use it with a lube. They use only Acijel OR Sylk. Sylk is a better lube than Acijel so I tend to recommend Sylk over Acijel, but yeah neither seem to be adding a whole lot.
