plannedparenthood: Dental dams are thin, square pieces of latex that help prevent STDs during oral sex on a vulva or anus. Dams protect you by keeping vaginal fluids out of your mouth, and preventing skin-to-skin contact between your mouth and a vulva. They also protect you during oral-to-anal sex from germs that can cause digestive infections. You can turn a condom into a dental dam! -- source link
