As tools to reduce risk for STI transmission, dental dams are not to be ignored.
Many consider oral sex to be a safer form of sexual activity compared to vaginal or anal intercourse. For this reason, they might put less emphasis on the use of latex barriers, such as dental dams and condoms, during oral sex. Unfortunately, this idea is misguided and can lead to the transmission of preventable infections.
It is generally true that oral sex presents less of a risk for contracting sexually transmitted infections (STIs) – but this risk is not trivial, especially when people are under the impression that they don’t need to use barrier methods during oral sex. Most sexually transmitted infections can be passed along by oral sex, including chlamydia, gonorrhea, syphilis, hepatitis B, herpes (which can be transmitted back and forth from the mouth, as cold sores, to the genital region, as genital herpes), human papillomavirus (HPV), and HIV. Even pubic lice can be transferred from the genital region to eyelashes and eyebrows! Additionally, intestinal parasites are more likely to be transmitted via oral sex than through vaginal sex. A microscopic amount of fecal matter containing parasites can be infectious, and can be unknowingly ingested when present on genitals.
Seventy percent of adolescents who reported engaging in oral sex had never used a barrier to protect themselves from sexually transmitted infections during oral sex.
Some bacterial STIs, such as gonorrhea and syphilis, can do permanent damage if not treated in time. Furthermore, gonorrhea of the throat is much more difficult to treat than gonorrhea in the genital or rectal areas. And some viral STIs can’t be cured (such as herpes and HIV), while others can cause chronic infections that have been linked to cancer (such as hepatitis, which is associated with liver cancer, and HPV, which is associated with throat cancer as well as cervical cancer and anal cancer).

Most sexually transmitted infections are caused by bacteria or viruses, but some are caused by organisms that are classified as completely different lifeforms. Trichomoniasis, for example, is caused by a protozoan organism; protozoa occupy their own kingdom, separate from plants, animals, and bacteria. Intestinal parasites are often protozoan organisms, but can also include parasitic worms (which are members of the animal kingdom). They are spread through contact with fecal matter – and as such, they can be transmitted sexually as well as nonsexually. Intestinal parasites are usually transmitted by fecal contamination of food or water, and are most common in areas with insufficient sewage treatment and untreated water in the wilderness. Some pathogens, however, have low infectious doses, making their sexual transmission more likely.
What has eight flagella and can live in your intestines?
Oral contact with the anus, also called anilingus or rimming, is the primary means of the sexual transmission of these pathogens. Putting fingers or hands in your mouth after they have had contact with the anus is also risky. Other modes of transmission include oral sex, as genitals can be contaminated with feces, as well as sharing sex toys and other equipment. For these reasons, it is very important to use dental dams or latex gloves during contact with the anus; to clean the anus before engaging in rimming; to clean or use condoms on shared sex toys; and to use condoms or dental dams during oral sex.
