Danish youth are having more sex, and better sex, than many assume—but a new national survey reveals systemic gaps in education, contraception, and access to trusted adults that leave many young people exposed to risk.
The narrative that today’s teenagers are having less sex than their parents’ generation doesn’t hold up in Denmark. A major new survey from Sex & Samfund shows that young Danes aged 15 to 25 are sexually active, satisfied, and generally knowledgeable about consent. The average age of sexual debut is 16.2 years, almost unchanged since the 1970s. Around 61 percent say their sex life is good or very good.
That’s the upbeat part. The report, called SexLiv 2025, also exposes troubling weaknesses. Too many young people use no contraception or unsafe methods. Too many never get proper sex education. And too many have no one to talk to about boundaries, pleasure, or fear.
The Reality Behind the Numbers
I’ve lived in Denmark long enough to know that progressive reputation doesn’t always match lived experience. The country prides itself on openness about sex, yet this survey makes it clear that openness doesn’t automatically translate into competence or care. SexLiv 2025 surveyed more than 1,300 respondents between May and June 2025. It’s one of the most comprehensive snapshots of young people’s sexual behavior in Denmark in recent years.
Sex education ranks as one of the top sources of information for young people, far ahead of chatbots like ChatGPT. But over half of respondents said they didn’t receive adequate education on sex, contraception, STIs, consent, or boundaries. That’s a system failure, not a generational quirk.
Consent Culture Is Strong, But Not Complete
Around 80 percent of sexually active youth say they can ensure consent during sex. That’s encouraging, especially given the public focus on consent since Denmark’s 2021 consent law. Young people today speak more fluently about boundaries than previous generations. They understand the principle.
But understanding and applying it in the moment are different things. Seventeen percent of young men and six percent of young women believe you cannot withdraw consent once sex has begun. That gap matters. It reveals that the conversation about ongoing consent, about changing your mind halfway through, still hasn’t fully landed.
As reported by Sex & Samfund, consent isn’t a checkpoint you pass once. It’s a conversation that continues. For some young people, that idea remains uncomfortable or unclear.
Contraception and Confusion
This is where the picture gets darker. Only about half of young men and a third of young women say they used a condom the last time they had sex with a new partner. One in seven used no listed contraceptive method at all. Withdrawal, what some call “pull and pray,” ranks as the third most common form of contraception among young people.
Denmark already has one of the lowest rates of condom use in the Nordic region. That’s not new. But combined with high sexual activity, it’s a public health risk. STIs like chlamydia remain concentrated among 15 to 29 year olds. The data from Statens Serum Institut backs that up. Young people are having sex. They’re just not protecting themselves consistently.
Sex & Samfund emphasizes that unsafe contraception leads to unintended pregnancies and disease transmission. The organization argues for better access, better education, and a cultural shift that makes condoms “sexy” rather than awkward. I’m skeptical that messaging alone will fix this. Access to free or cheap contraception, especially for students and apprentices, needs to be part of the policy mix.
Education Gaps and Missing Adults
Many young people have no trusted adult to talk to about sex. Depending on the topic, that’s one in four to one in seven respondents. Friends fill the gap, but friends aren’t trained counselors. They don’t know the facts about STIs or how to navigate coercion.
Sex education in Denmark is technically mandatory in primary school. In practice, it’s patchy. Quality depends entirely on the individual school and teacher. Some students get thoughtful, inclusive lessons about pleasure, identity, and respect. Others get a biology lecture and maybe a condom demonstration. The inconsistency is glaring.
I’ve watched expat parents struggle with this. They assume Danish schools have it covered. Sometimes they do. Often they don’t. And by the time you realize your kid didn’t learn about consent or healthy relationships at school, they’re already navigating those situations in real life.
A Broader Picture Coming
SexLiv 2025 zooms in on youth. But Statens Serum Institut and Aalborg University are currently running Projekt SEXUS 2, a massive study surveying a quarter million Danes aged 15 to 89 about sexual health and behavior. Results are expected later this year. That will show whether young people really are outliers or whether the patterns SexLiv identifies run through the entire population.
For now, the data tells a mixed story. Danish youth have active, generally positive sex lives. But the system meant to support them, educate them, and keep them safe is falling short. Schools aren’t delivering consistent education. Healthcare isn’t making contraception easy or affordable enough. And too many young people are navigating one of the most consequential parts of growing up without guidance.
Denmark likes to think of itself as a leader in sexual health and progressive values. This report suggests that reputation needs updating. The infrastructure is incomplete. The access is uneven. And
