When you think about sexually transmitted infections (STIs), also known as sexually transmitted diseases (STDs), you're probably thinking about those transmitted during vaginal penetrative sex. But oral sex and STIs are super common too. The Centers For Disease Control and Prevention (CDC) estimates that one in five people in the United States has an STI. And the same STIs that you can catch via penetrative sex (like gonorrhea, genital herpes, syphilis, and HPV) can be caught through oral sex too. So just to clarify, if you've ever asked yourself, "Can you get an STD from oral sex?" the answer is yes. Basically, you need to have your guard up regarding STIs no matter the sex you're having. But to get you get you caught up on all necessary information on oral sex STDs, we chatted with sexual health experts about whether oral sex is safe when it comes to STIs, oral sex STD signs, and the best ways to protect yourself.
"Safe" is a relative term, but when it comes to STIs, experts say that oral sex is not safe. "There is no such thing as completely safe sex," says Mary Jane Minkin, MD, a clinical professor of obstetrics and gynecology and reproductive sciences at Yale School of Medicine. She jokes that the only way to have completely safe sex is to "use a vibrator," and even that poses its own set of risks.
Dr. Minkin points out that you can't get pregnant from oral sex, but you can have other unintended consequences. That leads us to the next question.
Yup, you definitely can. In fact, the CDC warns about this online, noting that you can get an STI in or on your mouth, throat, genitals, or rectum if you're exposed to an infected partner. It's not just one or two STIs you have to worry about, either: "Many sexually transmitted diseases can be spread through oral sex," says women's health expert Jennifer Wider, MD.
According to the CDC, you can get STIs from oral sex in the following ways:
There are also a few factors that can increase your risk of getting an STI from oral sex. Dr. Wider lists the following:
There are actually a lot. The CDC lists gonorrhea, chlamydia, herpes, HIV, HPV, and syphilis.
Here's a breakdown of STI symptoms to look out for, according to the CDC:
You can initially get infected with chlamydia in the throat, genitals, urinary tract, or rectum, but most chlamydia infections in the throat have no symptoms. It's possible to have symptoms elsewhere, though, which can include:
Like chlamydia, most gonorrhea infections in the throat have no symptoms. But "you can get a sore throat from gonorrhea, just like a strep throat," says Dr. Minkin. Other symptoms, per the CDC, include:
Syphilis can be present without symptoms, or it can lead to the following signs, the CDC says:
Like syphilis, it's possible to have no symptoms with herpes. However, the CDC says you may have the following:
"HPV is a biggie" when it comes to STIs that can be transmitted via oral sex, Dr. Minkin says. In fact, this route of transmission is a growing cause of throat and mouth cancers, according to Harvard Health. With HPV, you may have no symptoms at all, or you might experience the following, per the CDC:
People with HIV may have no symptoms for many years, the CDC says. However, flu-like symptoms are an initial sign of infection.
It's important to "know your partner's history" and avoid having oral sex with them if they have an untreated STI, Dr. Wider says. Condoms can also be helpful in protection, Dr. Minkin says, along with dental dams, which go over the vaginal opening or anus like a big piece of plastic wrap. You can also cut open a condom to make a square and put it between your mouth and your partner's vagina or anus, the CDC says. Ultimately, experts stress the importance of prior proper planning. Oral sex can and should be enjoyable, but knowing your risk of getting an STI from oral sex and taking the proper precautions is the best course of action. And if you do think that you have an STI, be sure to get tested so that a healthcare provider can point you in the right direction when it comes to treatment.
