Easy to use, simply place the Glyde Dam over the area of the body you wish to perform oral sex and make sure any lubricant is on the body side and not the side your mouth will touch. These Sheer Glyde Dams are a silky thin barrier latex sheet and are perfect for vaginal and anal oral play. If you wish to perform oral sex in both areas, use two Glyde Dams. For single use only. Mixed Flavour pack includes Vanilla, Strawberry Wildberry and Cola.
