My wife and I have used three of the Astroglide lubricants so far. The first one, the regular Astroglide is great, much better than other brands we've used. But our favorite was the Paraben-free / Glycerin-free Astroglide, which has never caused any adverse reaction, no itching, and doesn't dry too fast either.
When the new all-natural version of Astroglide came out, we immediately tried it, hoping for an equally good experience PLUS all natural ingredients. But our first use of it proved somewhat disappointing, because of itching symptoms, white powder deposit on the skin when it dries and faster drying time. So we won't finish the bottle and will switch back immediately to our beloved Paraben-free / Glycerin-free Astroglide (which unfortunately comes only in small-volume bottles) !
