You already know that sex comes with a certain degree of risk. It could result in pregnancy, for starters. And it could also lead to an unwanted virus, fungus or bacteria. Roughly 20 million new sexually transmitted infections (STIs) occur in the U.S. every year, according to the Centers for Disease Control and Prevention (CDC).
What’s your best defense? Knowledge. It’s important to be educated about sexual health, says Maureen Whelihan, MD, a gynecologist in Palm Beach County, Florida. “But you should not focus on the risks of STIs to the point where you would avoid sexual intimacy, which is an integral part of wellness.”
Dr. Whelihan recommends that you familiarize yourself with the risk so you can build a strategy for managing it. And you can begin right here, with this quiz on sexual health.
Don’t worry if you answer some questions incorrectly. After all — you’re here to learn.

1. Which type of lubricant damages latex condoms?
A. Water-based
B. Oil-based
C. Silicone-based
D. All lubricant damages condoms
—

Answer: B
Latex is the most common material used in condoms, says Dr. Whelihan. But it doesn’t stand up to oil-based lubricants. Using anything with petroleum jelly, baby oil, coconut oil or mineral oil can increase the risk of breakage, according to the Mayo Clinic. So if you’re using a condom, stick with silicone- or water-based lubes.
There is, of course, an exception to the rule. People who are allergic to latex may use polyurethane condoms instead. In this case, oil-based lubricants are safe, says the CDC.

2. Which of these is the most effective form of contraception?
A. Intrauterine device (IUD)
B. Diaphragm
C. Condom
D. Birth control pill

Answer: A
An IUD is a device that your nurse practitioner or doctor places into your uterus. You can have it taken out at any time, but if you choose not to, it will last for years.
The primary benefit of IUDs, according to Planned Parenthood, is that they leave little room for human error. People can use condoms incorrectly or forget to take pills. But once an IUD is in, it’s in.
Because of that, fewer than 1 in 100 women with IUDs become pregnant each year, according to the American College of Obstetricians and Gynecologists. Women who count birth control pills as their primary contraceptive don’t fare as well. About 9% become pregnant. With diaphragms, it’s 12%, and with condoms, it’s 18%.
That’s not to say pills, diaphragms and condoms aren’t reliable. They’re just more prone to error, says Mary Jane Minkin, MD. She’s a clinical professor in the department of obstetrics, gynecology and reproductive sciences at the Yale School of Medicine.
Take diaphragms, she says: “If a woman uses it properly every time she has sex, it can be very effective. But this means inserting it an hour before having sex and keeping it in for 6 to 8 hours after sex. We’re human, so we don’t always follow the directions to a T.”
3. What is the most common STI in the U.S.?
A. human papilloma virus (HPV)
B. Chlamydia
C. Gonorrhea
D. Herpes

Answer: A
“HPV is far and away the most common sexually transmitted infection in the U.S.,” Dr. Minkin says. In fact, about 79 million Americans are currently infected, according to the Cleveland Clinic.
One reason HPV is risky is that it often causes no symptoms, so it’s hard to detect. And certain strains can lead to cancer. According to the National Cancer Institute, HPV is responsible for 60% of penile cancers, more than 90% of anal cancers and virtually all cervical cancers.
But just because you have HPV doesn’t necessarily mean your cancer risk is elevated. Most strains pose no serious risk to your health, according to NYU Langone Health. But even non-carcinogenic strains can cause genital warts, which can be uncomfortable or embarrassing. In 90% of cases, the infection will go away or drop to an undetectable level within 2 years, notes the hospital. (Here’s how to get tested and treated for an STI even if you don’t have insurance.)
Fortunately, you can avoid this problem: There is an HPV vaccine available. The CDC recommends that children and young adults receive it between the ages of 9 and 26. If you’re older than 26, you and your doctor can discuss whether you need the vaccine.
4. Which STIs does a routine Pap smear screen for?
A. HPV
B. Gonorrhea
C. Chlamydia
D. None of the above
—
—
Answer: D
A Pap smear does not routinely test for STIs. Rather, it collects cells from your cervix and examines them for changes caused by HPV. This can help detect cancer. But the test does not look for HPV itself. You could have no signs of cervical cancer but still have HPV — or any other STI, for that matter.
If you’re concerned about STIs, let your gynecologist know before your Pap smear, says Dr. Minkin. The 2 of you can discuss your sexual history and decide which STIs it makes sense to screen for alongside the exam.
