Thanks for the above link. Very informative!

I was sold on glycerin until I read this section:
Glycerin is related to the sugar glucose. If you taste some, you will see that glycerin lubes are sweet. Like sugar, glycerin is a good energy source and sometimes serves as a nutrient for microbes. Women may find that glycerin lubes foster yeast infections. If you or your lover suffers from frequent vaginal infections, look for glycerin-free water-based lubes. There are several other molecules that can hold water together as glycerin does, without feeding populations of vaginal bacteria and fungi.
I was prone to yeast infections once upon a time and have no desire to ever repeat that cycle.
Sooo... what is the scoop on aloe vera???
