I decided on silicone-based over water-based lubes a long time ago because they are never sticky or tacky and have absolutely no smell or taste. After experimenting with sever different brands, I discovered that Millennium ID is the best personal lubricant out there. This purchase was an incredible deal since I usually pay more than double at the adult stores around here. The pump is quite handy. If you are not accustomed to silicone lubricants, be aware that a very little goes a long way and that this product can stain many fabrics. For me, the advantages out weight those disadvantages.
