Talking to Teens About Sex: What Parents, Teachers, and Caregivers Need to Know

Posted: November 12, 2025

Talking about sex with your teenager can feel uncomfortable, overwhelming, or even unnecessary but as a therapist with more than 20 years of experience working with teens and families, I can assure you that these conversations are essential. Whether you’re a parent, teacher, counselor, or grandparent, your voice matters. Teens today are bombarded with misinformation from social media, peers, and internet searches. Yet, many are too afraid or embarrassed to ask the trusted adults in their lives. When we open the door to honest, nonjudgmental communication about sexual health, we give our teens the tools to make safe, informed, and respectful decisions about their bodies and relationships.

Why Teen Sexual Education Starts With YOU

Too often, I hear teens ask me questions like, “What does intercourse even mean?” or “Can I get pregnant from oral sex?” These are real concerns, and unfortunately, many teens are too embarrassed to ask at home. When accurate information is not provided by trusted adults, they turn to unreliable sources such as friends, TikTok, or Google.

As a parent or caregiver, you are in a unique position to set the tone for these discussions. Here’s what you should know and how you can guide your teen’s sexual education journey.

Common Questions Teens Ask About Sex and How to Answer Them

1. What is “intercourse”?

Many teens do not understand the basic definition of intercourse. Use clear, age-appropriate language: Intercourse typically refers to vaginal sex, where a penis is inserted into a vagina. However, there are other types of sex, including oral sex and anal sex, and all carry different levels of risk.

2. Types of Sex: What Should I Explain?

Educate your teen on:

Vaginal sex: Can lead to pregnancy and STIs.
Oral sex: Cannot cause pregnancy, but can transmit STIs.
Anal sex: Cannot cause pregnancy, but can transmit STIs.

Use medically accurate terms and avoid euphemisms that cause confusion. Let your teen know no question is off-limits.

3. Can I Get Pregnant From Oral Sex?

No, pregnancy cannot occur from oral sex. However, oral sex still carries the risk of STIs like gonorrhea, chlamydia, and HPV. Teens often mistakenly believe oral sex is “safe,” but it’s important to clarify the differences in risks.

4. Does the Pull-Out Method Work?

The "pull-out method" or withdrawal method is not a reliable form of birth control. According to the CDC, about 22 out of 100 people who use this method will become pregnant each year. Teens need to understand that even pre-ejaculate can contain sperm which can lead to pregnancy, and that this method does nothing to protect against STIs.

5. Can Tracking Ovulation Prevent Pregnancy?

Some teens believe that tracking ovulation [also known as the fertility awareness method (FAM)] is a reliable way to avoid pregnancy. This method involves identifying the days in the menstrual cycle when a person is most fertile and avoiding unprotected sex during that window. People may track ovulation by monitoring:

Basal body temperature (BBT) daily upon waking
Cervical mucus changes throughout the cycle
Cycle calendar (counting days and estimating ovulation)

But Is It Safe or Effective for Teens?

While fertility tracking can be effective for adults with very regular cycles and perfect tracking habits, it is not recommended as a primary form of birth control for teens for several reasons:

Teen cycles are often irregular, especially in the first few years after menstruation begins.
Fertility signs (like cervical mucus and temperature) can be difficult to monitor accurately.
Even under ideal circumstances, this method has a failure rate of about 24% per year with typical use, according to the CDC.

Does It Protect Against STIs?

No. Fertility awareness methods offer zero protection against sexually transmitted infections (STIs). This is a crucial point to help teens understand. Even if they’re using FAM to prevent pregnancy, they are still at risk of STIs if they have unprotected sex.

Healthier Alternatives

Teens who are sexually active (or even thinking about becoming sexually active) should be educated about safer, more reliable forms of birth control and STI protection. This includes condoms, which offer both pregnancy and STI protection.

6. Does the HPV Vaccine Protect Me from All STIs?

The HPV vaccine is a powerful tool for preventing certain types of human papillomavirus (HPV), a group of viruses that can cause genital warts, cervical cancer, and other types of cancer (such as throat, penile, and anal cancers). The most common HPV vaccines (like Gardasil 9) protect against the 9 most dangerous strains of HPV, including those most linked to cancer.

However, it’s critical for teens and caregivers to understand:

The HPV vaccine does NOT protect against all STIs. It is only effective against HPV, not chlamydia, gonorrhea, herpes, HIV, syphilis, or other infections.
Condoms and dental dams are still essential for reducing the risk of most STIs, including those the HPV vaccine doesn’t cover.
Getting the vaccine is still highly recommended for all teens (regardless of gender) and is most effective before sexual activity begins, but it's never too late to ask a doctor if it’s right for your teen.

Bottom line: The HPV vaccine is one important piece of STI prevention, but it’s not a complete shield. Open, informed conversations about comprehensive protection are still crucial.

7. Understanding STI Risk with Multiple Partners

Many teens assume that if their partner “looks healthy” or doesn’t mention any symptoms, they must be STI-free. Unfortunately, this is a dangerous misconception. Most sexually transmitted infections (STIs) including chlamydia, gonorrhea, herpes, and HPV can be completely asymptomatic, meaning a person can have and spread an STI without knowing it.

The risk of contracting an STI increases with the number of partners a person has especially if barrier protection (like condoms or dental dams) isn’t consistently used. Each new partner brings potential exposure to the partners they’ve had before, even if they have no visible symptoms.

This is why regular sexual health screenings, open conversations, and consistent condom use are essential. Teens should understand that trusting someone isn’t the same as knowing their STI status.

How to Supervise Teens to Prevent Risky Behavior

According to the Guttmacher Institute, most teens who report having sex do so at home after school or in a partner's home when parents are not around. This means unsupervised time is a key factor. Some simple strategies include:

Know your teen's plans and who they’re with.
Set boundaries around private time in bedrooms.
Encourage open communication about relationships and expectations.

Tips for Supporting Teens in Their Sexual Health Journey

✅ Create Opportunities for Medical Privacy

When taking your teen to their pediatrician, PCP, or OB-GYN, let the provider know you’ll step out early to give your teen a chance to ask questions privately. Even if they don’t ask right away, you’re sending a clear message to your teen: you trust them, and they have permission to learn independently from a trained medical professional.

✅ Give Access to Protection

Many teens do not have transportation, money, or the courage to buy condoms. Buy them for your teen. Store them somewhere private and accessible. Research from the American Academy of Pediatrics shows that access to birth control does not increase sexual activity, but it does increase safety and responsibility.
