Hey smudge,

It's actually an internal lubricant...similar to the consistency of EWCM...so apart from adding to the "enjoyment" of the experience, it also is actually supposed to nourish the sperm and provide an optimal sperm enviroment!!!

You can order it through lullaby conceptions (they advertise on BB)...for 6 vials, it's about $30...so it's not something you use everyday...but on special O days!!!

Good luck!
