Ask a group of 16-year-olds when they first saw porn and many will say 11, 12 or 13. Most will say they weren't even looking for it: it just appeared on social media or was sent in a group chat. For a whole generation, porn has become an unofficial, unasked-for sex education. What does that do to expectations, to self-image and to real relationships?
It usually finds young people first
In 2025, the Children's Commissioner for England surveyed young people aged 16–21. 70% had seen porn before turning 18, up from 64% in 2023. 59% said they had come across it by accident, up from 38%. The average age of first exposure was 13, and 27% had seen it by age 11. The most common source wasn't a porn site at all: it was X (formerly Twitter), where 45% had seen porn, compared with 35% on dedicated porn sites.
A US survey of 13–17-year-olds found a similar picture: 73% had seen porn, the average first age was 12, and 45% said porn gave them "helpful" information about sex. Only 43% had ever talked about it with a trusted adult. In Ireland, a 2026 study of over 5,000 teenagers found that 37% had used porn in the past year, including half of the boys.
For parents, the uncomfortable takeaway is that the first exposure usually comes through ordinary social media, often before any conversation has happened at home. Waiting for "the right age" to talk usually means talking too late.
What it teaches, and what it leaves out
Mainstream porn is a performance made to excite, not a guide to real intimacy. It usually leaves out conversation, consent, tenderness, awkwardness, contraception and ordinary bodies. And much of it is aggressive. In the English survey, 58% of young people had seen content showing strangulation before the age of 18, mostly without looking for it. If you're young and have seen something like this, it doesn't mean something is wrong with you. But it's not what real partners expect, and pressure on someone's neck is dangerous, even when it's presented as play.
The same survey suggests these messages stick. 44% agreed that "girls may say no at first but then can be persuaded to have sex." Agreement was higher among those who had seen porn (54% of girls and 41% of boys) than among those who hadn't (46% and 30%). And 82% said porn had affected their expectations around sex. This is a survey, so it shows a link, not proof of cause, but the pattern is worrying. To be completely clear: "no" means no, the first time.
Young people's wellbeing
A 2026 review pulling together 12 studies of 10–19-year-olds found a moderate link between online porn use and psychological symptoms such as anxiety and low mood, similar for boys and girls. The Irish study linked teen porn use with riskier sex, such as sex without a condom and starting sex very early, and found that parental involvement was protective. These studies show associations: young people who are struggling may also turn to porn more. But together they suggest that early, heavy exposure is not a neutral experience.
Adults: it depends on why you watch
For adults, the evidence is more mixed, and it's important to say so. A 2026 review of 21 studies with over 138,000 people compared men and women who use porn. Male users reported lower sexual satisfaction and more sexual difficulties than female users. These are snapshots in time, so it may also run the other way: people with sexual difficulties may turn to porn more.
One of the most useful recent studies followed 327 couples for 35 days, with both partners keeping a daily diary. What mattered most was why someone watched. On days a person used porn to escape stress or distract themselves from feelings, they were less warm and more negative toward their partner. On days it was about pleasure or connected to their partner, the day looked the same or better. And on days one partner used porn, the other tended to be a little less warm too.
What therapists see most often isn't porn on its own destroying relationships. It's secrecy, mismatched expectations and comparison: comparing a partner's body, or your own, with performers, or expecting real sex to look like a script. Open conversations, without shame on either side, tend to help more than silence.
It can affect self-image quietly too. Porn shows a very narrow range of bodies, reactions and "performance." Young men may start worrying that they don't measure up. Young women may feel they're expected to look and act in ways that have little to do with their own wishes. Neither reflects how ordinary people look, feel or enjoy intimacy, but when porn is your main reference, the gap can feel like a personal failure.
Key numbers
- Age 13 is when young people typically first see porn, and 1 in 4 has seen it by age 11. Children's Commissioner for England, 2025
- 6 in 10 young people came across porn by accident, most often on social media rather than porn sites. Children's Commissioner, 2025
The bottom line
The biggest risk isn't that people see porn. It's that, for many, it becomes their main teacher about sex and relationships, often from age 11–13, before any real conversation has happened. Whether you're a teenager, a partner or a parent, the most protective thing is the same: talking honestly. Talk about consent, respect, real bodies, and the difference between a performance and real intimacy.
Quick self-check
- Has porn shaped what you think sex "should" look like?
- Do you compare your body, or your partner's, with what you see in porn?
- Is porn something you hide from a partner, and does that secrecy cause tension?
- Do you mostly turn to porn to escape stress or difficult feelings?
- Have you ever had a calm, honest conversation about porn with someone you trust?
This is not a diagnosis. These questions are meant to open reflection and conversation.
If porn is affecting your relationship or how you see yourself, couples therapists and sex therapists deal with this often. Asking for help is normal. If something you saw online upset or frightened you, tell an adult you trust.
