How Do You Teach Boys About Sex? It’s Alive! A Parent’s Guide to Bodies, Boundaries, and Puberty
“It’s alive! IT’S ALIVE!”
Okay, maybe Frankenstein wasn’t talking about puberty, but if you’ve ever raised a young boy who suddenly discovered that his penis can apparently change size without consulting him first, the comparison isn’t that far off.
A colleague of mine told me about the moment her young son started getting erections. He would look down in complete astonishment and announce, “Why is it so big? What happened? My penis is so big!”
And there it was. It was alive. Not in the horror-movie sense, obviously, but in the completely normal, healthy, "Welcome to having a human body," sense.
These are actually the moments when sex education begins. It doesn’t begin when you sit your teenager down at the kitchen table with a banana and a condom, and it definitely doesn’t begin five minutes before your kid starts dating. Sex education happens in hundreds of little moments as our children grow. It happens with a surprising erection, a question about where babies come from, animals mating in a book, a first crush, a first rejection, a first kiss, or questions about puberty, attraction, consent, masturbation, relationships, condoms, pregnancy, STIs, and eventually sex itself.
The monster doesn’t suddenly awaken at 16. Their bodies, curiosity, relationships, and sexuality have been developing all along. Our job isn’t to be terrified of the monster. It’s to teach our kids how to understand being human.
Is a Condom and a Banana Really Sex Education?
Recently, I appeared as a therapist on Double Lives of Suburban Housewives, Season 1, Episode 5. In that episode, there’s a scene where a mom attempts to teach her teenage son about sex using those classic sex-ed props: a condom and a banana.
As a sex therapist watching the scene, I couldn’t help thinking, "We’re skipping about 47 steps here." Interestingly, the conversation doesn’t even get as far as having him practice putting the condom on the banana.
Don’t get me wrong. I absolutely want young people to learn how to use condoms correctly. When they are developmentally ready for that information, practical safer-sex education matters. But handing a teenage boy a condom doesn’t magically teach him how to navigate sexuality. There is so much that happens before the condom ever enters the picture.
How does he know if somebody likes him? How does he tell someone that he likes them?
How does he ask someone out? What happens if they say no?
How do you kiss someone? How do you know if they want to kiss you?
What is happening to his body?
Why is he suddenly thinking about sex?
What does he do when he’s attracted to somebody?
What does consent actually sound like?
How does he communicate a boundary or respond when someone else gives him one?
How does he know whether he is actually ready to have sex?
Then, eventually, yes, we can get to: "How the hell do I put this condom on?"
The banana is somewhere near the end of a much longer conversation.
When Should Parents Start Talking to Boys About Sex?
The good news is that you don’t have to wake up one Saturday morning, pour yourself a giant cup of coffee, sit your 13-year-old down at the kitchen table, and announce, “TODAY WE DISCUSS SEX.” Please don’t do that to yourself, or him.
Sex education can happen organically throughout childhood and adolescence because bodies, relationships, reproduction, affection, attraction, and boundaries are already showing up in your child’s everyday life.
Another story from this same colleague illustrates this beautifully. She was reading with her other son when they encountered something about animals mating and reproducing. She had been intentionally trying to become more comfortable taking opportunities to talk with her boys about bodies and sex, so she thought, "Okay, here’s my opening." She explained that humans reproduce through sex, too.
Her son was stunned. Wait. Humans do that? Then came the question every parent dreams of answering: “Did YOU do that?” Well...yes. That’s kind of how you’re here.
His mind was blown. She gave him an age-appropriate explanation of anatomy and intercourse, including that one way people have sex involves a penis going inside a vagina.
Her son sat with this shocking new information about the human species and finally announced, “I’m gonna have to worry about that for the rest of my life.”
Later, she told her husband what their son had said, and Dad’s response was basically, “Yeah, that’s pretty accurate.”
Welcome to humanity, kid.
What I love about both of these stories is that neither mother needed to manufacture some elaborate sex-education lesson.
Life handed her the lesson.
One child was discovering, My body does things.
The other was discovering, Humans do things with their bodies.
Both needed an adult who could respond without treating the discovery like something frightening had just crawled out of the basement.
Bodies, Boundaries, and Puberty
When I think about teaching young boys about sexual health, I like starting with three broad areas:
Bodies,
Boundaries, and
Puberty.
Bodies means teaching accurate names for anatomy, helping children understand how their bodies work, talking about privacy, and creating a sense of body neutrality. A penis is a penis. An erection is something a penis can do. Having an erection doesn’t automatically mean something is wrong, and noticing or asking questions about your own body isn’t something shameful.
Boundaries are just as important, and we can teach them long before a child has any interest in sex. Your body belongs to you, and other people’s bodies belong to them. We can teach children to ask before touching, listen when somebody says no, communicate discomfort, respect privacy, and understand that affection and physical contact aren’t something they are automatically owed. Those lessons become the foundation for much more complicated conversations about consent later.
Then there’s puberty, when suddenly the horror-comedy really kicks into gear. Erections. Body hair. Ejaculation. Wet dreams. Changing voices. Body odor. Attraction. Sexual thoughts. Bodies start doing all sorts of things kids didn’t exactly request. The more information they have before and during these changes, the less likely every new development has to feel like, OH MY GOD, WHAT IS HAPPENING TO ME?
Or, in our horror-movie terminology: IT’S ALIVE!
Boys Need Relationship Education, Too
One of the biggest pieces I think we miss when teaching boys about sex is relationship education. Sometimes we jump directly from puberty to pregnancy and disease prevention. We teach boys what not to do: don’t get someone pregnant, don’t get an STI, don’t pressure somebody, don’t have sex before you’re ready. Those conversations matter, but where are we teaching boys what to do?
A teenage boy can genuinely want to be kind and respectful and still have absolutely no idea how to navigate attraction. We can talk with boys about what it feels like to have a crush, how to tell somebody you like them, how to ask someone out respectfully, how to flirt, and how to recognize whether another person seems interested. We can talk about kissing before they are standing six inches from somebody’s face trying to figure out what the hell happens next. We can teach them that nervousness is normal and that communication doesn’t ruin romance.
We can also teach boys how to experience rejection. Another person’s attraction isn’t something you earn by being nice enough, buying enough things, or waiting long enough. “No” isn’t an invitation to negotiate until you get a yes.
At the same time, boys need to know that they get to have boundaries, too. They can change their minds. They don’t have to participate in sexual experiences to prove something about their masculinity. They don’t have to be ready simply because an opportunity presents itself.
Consent belongs inside this larger relationship conversation. Good sexual communication doesn’t magically appear once everyone’s clothes come off. It develops through all of these earlier experiences of asking, listening, communicating, noticing, respecting boundaries, and tolerating disappointment.
By the time we get to condoms, we should already have been talking about relationships for years.
Your Reaction Is Part of Your Child’s Sex Education
This is where parents have to look inward, because your child isn’t only listening to the words coming out of your mouth.
He is watching your face. If he asks a question about his penis and your eyes get huge, you gasp, shut down the conversation, or act like he has said something disgusting, you have communicated something even if you never intended to. If he asks about sex and you immediately panic, that communicates something, too. If you answer calmly and matter-of-factly, you are also teaching him something: This is something we can talk about.
That doesn’t mean you need to become the world’s most sexually liberated parent who joyfully discusses erections over pancakes every Sunday morning.
You are allowed to feel awkward. In fact, you can be honest about it. You might say, “That’s a good question. Nobody talked to me very well about this stuff when I was growing up, so sometimes I feel awkward talking about it. But I want you to know that you can ask me questions.”
That is sex education, too. You don’t have to know everything. You need to become someone your child believes they can come back to.
Sometimes Parents Need Their Own Sex Education First
This is one of the reasons I wrote From Fck No to Fck Yes Sex! Although the book is for adults, much of it explores our relationships with our bodies, sexuality, shame, and the messages we accumulate throughout our lives. I also share pieces of my own experience raising my child and intentionally working toward body neutrality, because our own relationship with sex inevitably affects the way we talk about it with our children.
The uncomfortable truth is that we teach sex education from inside our own sex education. If sex was treated as shameful in your family, that comes into the room. If nobody taught you accurate names for body parts, that comes into the room. If sexuality was only discussed as dangerous, sinful, embarrassing, secretive, or something you weren’t supposed to want, that comes into the room. If you have spent years at war with your own body, some of that can come into the room, too.
You don’t have to resolve every piece of your own sexual history before you can be a healthy parent. Becoming aware of it, however, matters. Body neutrality and sex neutrality give us another way to approach these conversations.
Instead of teaching children that every sexual thought, question, or bodily change has to be immediately categorized as GOOD or BAD, we can begin somewhere much simpler:
This is a body. Bodies do things. Sexual development is part of being human. You have choices about what you do with your body. Other people have choices about theirs. And we can talk about it.
Don’t Wait for the Banana
Eventually, yes, bring out the condom. Bring out the banana. Better yet, when your teenager is developmentally ready, actually teach the practical skill rather than waving the condom around and hoping everyone understands the assignment.
But please don’t let that be the beginning and end of your son’s sex education.
The goal isn’t simply to raise a boy who knows how to avoid a pregnancy or an STI. We are trying to raise young men who:
understand their bodies,
communicate their needs,
respect other people’s boundaries,
tolerate rejection,
recognize consent,
make thoughtful sexual decisions, and
know that they can ask for help when they don’t understand something.
That education doesn’t happen during one terrifying conversation. It happens when an animal mates in a children’s book. It happens when a little boy discovers his first erection and screams that his penis got huge. It happens when he develops his first crush, when somebody likes him, when somebody doesn’t, when he wants his first kiss, when puberty arrives, when sexual feelings arrive, and eventually, yes, when the banana arrives.
So when the monster starts awakening, you don’t have to panic. You don’t have to run from the room screaming, and you certainly don’t have to have all the answers.
Stay curious. Stay calm. Keep talking.
Because if there’s one thing scarier than discovering, “IT’S ALIVE!”, it’s realizing nobody ever taught you what to do with it.
