Query: Best lubricant

I have tried KY and astroglide products and they are all terrible because they don't last and get sticky. Liquid Silk is the best lubricant ever! It never gets sticky and a little bit goes a LONG way. You put it on, it lasts, and it feels good. This is by far one of the best things I have ever purchased. Plus the pump is really convenient.
