Swirl is a group of flavored water-based lubricants, all glycerin and paraben free. All Swirl formulations start with the Sliquid H2O lubricant, and add flavoring and a hint of aspartame to sweeten. Their flavors are subtle, and are intended to enhance your taste, not disguise. Sometimes the mouth needs lubing up, as well! Can be used safely during oral, vaginal or anal sex. 4.2oz
