A retired family physician explains why sex ed has always been broken — and what teaching the clinical truth about human biology actually looks like.
Most of us have a cringey sex ed memory.
Mine involves a very perky, very anxious health teacher who had exactly one goal: scare us out of getting pregnant or getting an STD.
That’s not education. That’s a threat with a filmstrip.
Whether the awkward conversation happened at school or at home, the pattern was almost always the same. An adult who didn’t want to be there, didn’t know the actual science, and spent the whole time hoping you wouldn’t ask anything real. The information was thin. The fear was thick. And most of us walked away knowing roughly nothing useful about how our bodies actually work.
As a physician, I spent decades watching what happens next. Parents would bring their kids to my office wanting better information for their children — and then end up learning things they’d never been told either. Kids watching their parents have genuine breakthrough moments. Everyone in the room realizing, at the same time, how much they’d been left out of.
That’s not a coincidence. It’s a consequence.
I became a sex ed teacher entirely by accident
I was a precocious child. I picked up a lot of details about human biology from the Old Testament — which, if you read it as a human document rather than a sacred text, contains an astonishing amount of graphic information — and from the anthropology books my mom kept in the basement.
But I still felt completely unprepared for puberty. None of that was in the books.
The education gap really became obvious when my younger brother needed the talk and my stepfather lasted approximately one minute in that bedroom before bolting out. So I went in. With a biology textbook, zero personal experience, and a fairly clear sense of the actual science.
I explained genetics first. Then why genetic diversity matters. Then how that exchange happens — as one part of the story of making another human, not the main event. Then contraception. Then the fact that people have sex for reasons other than reproduction.
He thought that last one was completely insane.
But none of it felt shameful. Because I wasn’t starting from shame. I was starting from biology.
I ended up doing this for my other brothers too. And somewhere in there, I realized: this was the right way to do it. Not because I was particularly skilled. Because I was starting in the right place.

What medicine taught me about not telling people what to do
When I got to medical school, I brought my opinions with me. Most 20-year-olds do.
My third-year rotation in outpatient internal medicine fixed that fairly quickly.
My attending sent me in to talk to a patient about quitting smoking. He smirked slightly as he sent me in. I didn’t understand why yet.
The patient — Mr. Simpson — had been smoking since he was ten years old. He was not interested in my thoughts about that. He told me, at length, that I was too young to tell anyone anything, that I’d never smoked, and that I had no idea what I was talking about.
He was right on all three counts.
So instead of defending myself, I agreed. I told him I had no right to tell him what to do. That quitting sounded genuinely harder than anything I’d ever done. That I couldn’t imagine what his life had been like to start at ten.
He kept arguing. I kept listening.
A few days later he came back — this time struggling to breathe after a bad stretch. Still insisting he wasn’t going to quit.
On my last day of the rotation, a nurse found me. Mr. Simpson was scheduled with another doctor, she said, but he was asking for me specifically.
He told me he quit.
Not because I told him what to do. Because I didn’t. Because I sat with him and acknowledged that it was hard and that his life was his own. He didn’t need another person explaining the dangers of smoking. He already knew. He needed someone to stop telling him what to do long enough to actually hear him.
That became a rule I carried through the rest of my career: if I couldn’t understand why a patient was making the choice they were making, I was missing information. Everyone is internally consistent. My job was to keep listening until it made sense.
Why starting from clinical truth changes everything
The same principle applies to how I design curriculum.
I’m not here to tell kids what to do with their bodies. I’m here to make sure they actually understand them.
That means starting from embryology, not from the act. It means explaining that we all begin as a single cell — which is not an opinion, it’s a fact — and building outward from there. It means trusting learners with the real information instead of a simplified version that has to be untaught later.
Take differences of sexual development. The culture wants to make that a political fight. But start from embryology — start from the fact that all embryos begin from the same basic template, then follow a sequence of signals that usually leads to typically male or typically female anatomy — and suddenly it’s not a fight. It’s biology. If any step in that sequence varies, you can get differences in development. That’s observable. That’s clinical reality. The science was always there. We just weren’t taught it.
What happens when people finally understand
One of my first video editors texted me a photo of her grocery cart.
She said: look what you made me do.
She’d been editing my anatomy and physiology lessons — only through heart, lungs, and the digestive system. And she told me: now I understand my organs. They feel like pets I need to take good care of. So I want to feed them properly.
Not because anyone told her to. Because she understood why.
That’s the difference between being told what to do and actually understanding something.
When people understand how their bodies work — when they understand how other people’s bodies work, and why none of this is shameful or bizarre, because it’s just biology — the behavior shifts. From guilt to knowledge. From fear to curiosity.
Humans are, physically, not impressive animals. We’re soft. We’re slow. We don’t have claws. We have survived this long not because we’re individually powerful but because we work together. Archaeologists find this in the oldest human remains: people with catastrophic injuries who survived for years, because someone else kept them fed and alive. Compassion isn’t a nice extra. It’s the survival strategy that got us here.
That’s who we are. A species that watches out for each other.
And when we teach clinical truth — when we replace the shame and the silence and the fear with the actual science of how incredible every human being is, from that very first single cell — we get to be that species more fully.
That is why I’m teaching clinical truth.
