Step 1
Understand the purpose of the dental dam. The dental dam is a thin piece of latex or silicone used to prevent the spread of sexually transmitted diseases.
-
Step 2
Buy or make your own dental dam. Dental dams can be found online but they tend to be pricey. To make a dental dam, cut a condom lengthwise and then proceed to shape it into a square with the scissors. If you choose to use a condom, be sure that it is not one that has spermicide or other chemicals as part of its make up.

Step 3
Place the dental dam over the clitoris, labia, vagina or anus before applying your mouth to the area. The dental dam will provide a barrier between your mouth and nose and any bacteria or germs that are on the surface of the area you are performing oral sex on.

Step 4
Use a new dental dam each time you change areas or partners. When it doubt, throw it away and break out a new one.
