STD Awareness: “Can I Get an STD from Oral Sex?”

As tools to reduce risk for STD 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 diseases (STDs) — 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 diseases 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 STDs during oral sex.


Some bacterial STDs, 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 STDs 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).
