Dental Dams Dental Dams are thin squares of latex usually used by dentists. However, dental dams may be hard to find, cost too much, and are limited by their small size. They are available through dental and medical supply stores, condom supply stores, and the University Health Center Pharmacy. If dental dams are unavailable, non-lubricated condoms can be used in their place by unrolling and cutting along the length. This will provide a small piece of latex.
Plastic wrap is cheaper and more widely available than dental dams.
It is also thinner, making heat and sensation stronger. Just remember, like latex, plastic wrap can rip. Also, one should use non-microwavable plastic wrap, as the microwaveable kind is porous. Place the lubricant on one side of the dam or wrap and place that side on your partner. Cover the labia, vaginal opening and clitoris, holding the two edges of the dam with your hands.
