Underage Sex: How to Protect Your Children

What the law says about underage sex

The age of consent in England, Scotland, Wales and Northern Ireland is 16. Sexual activity with anyone below this age is a criminal offence, regardless of whether both people are under the age of consent.

Sexual activity is defined broadly under UK law. It includes penetrative sex, oral sex, and sexual touching or masturbation. The law applies equally to heterosexual and homosexual activity.

The law also makes specific provisions for positions of trust. Adults who work with young people, such as teachers, coaches or care workers, commit an offence if they engage in sexual activity with anyone under 18 in their care. This applies even though 16 and 17 year olds are above the general age of consent.

Prosecutors and police consider the circumstances carefully before deciding whether to take action. Two 15 year olds in a relationship will usually be treated very differently from an adult who targets a child. But the activity remains illegal, and law enforcement takes all cases seriously.

How cases are handled in practice

The Crown Prosecution Service has guidance on approaching cases involving young people. Factors that influence a decision include the ages of those involved, whether there was any coercion or manipulation, and the nature of the relationship.

Where both parties are of similar age and the activity was genuinely consensual, a prosecution may not be considered in the public interest. This does not make the activity legal, and formal criminal proceedings can still follow.

Where there is a significant age gap, or where any form of pressure or exploitation is involved, the situation is treated far more seriously. Sentences for sexual offences against children can include lengthy prison terms and placement on the sex offenders register.

Parents should understand that even if no prosecution takes place, a referral to social services or other agencies may still occur if professionals become aware of underage sexual activity.

Your situation may be slightly different. ask a question below ↓ and our editorial team will reply with our advice.

Talking to your children

This is difficult territory for most families. Some parents feel that frank conversation helps keep children safer. Others prefer to emphasise that sexual activity should wait until the legal age or later. This article does not advocate for any particular approach.

What most professionals agree on is that children benefit from understanding the law and the potential consequences. They should know that sexual images of under 18s are illegal to take, share or possess, even if they created the images themselves. This is covered by laws on indecent images of children.

The concept of Gillick competence is also relevant here. This legal principle recognises that some young people under 16 may be mature enough to consent to medical treatment, including contraception, without parental involvement. It does not change the age of consent for sexual activity, but it does affect how health professionals can advise young people.

Organisations such as the NSPCC and Childline offer resources for parents and young people on these topics. Schools also cover relationships and sex education as part of the curriculum, though the depth and approach varies.

Where to find further information

For legal detail on sexual offences and the age of consent, GOV.UK and the Crown Prosecution Service website provide official guidance. The Sexual Offences Act 2003 sets out the framework for England and Wales, with separate but similar legislation in Scotland and Northern Ireland. Readers should verify current details as legislation can change.

If you are concerned about a child's safety or believe a child may be at risk of exploitation, you can contact:

  • The NSPCC helpline on 0808 800 5000
  • Childline on 0800 1111 for children and young people
  • Your local police or social services

These conversations are rarely easy. Knowing the legal framework can help, but talking about sex with your children will probably still feel awkward. That is normal.

@Mrs C Tan You've raised a serious concern, and it deserves a straight answer rather than a PR line. Could you point to the specific policy wording you're referring to? I've had a look through our current guidance and can't find anything permitting adult males to supervise girls changing, so I'd like to check whether this is our page or something you've seen elsewhere being attributed to us. Single sex spaces are protected under the Equality Act 2010, and we're bound by that same law.
Mrs C Tan 15/09/2026 at 4:00 pm
WHY ARE YOU ALLOWING BIOLOGICAL MEN IN GIRLS CHANGING ROOMS?.
I understand you will be allowing biological men to watch over young girls changing in changing rooms. That your revised policies now allow this where they did not before. I will no longer fund you in any way. You will be contributing to the very cause you claim to save.
I request that you revoke your new policy and change it back, in order to safe guard children. We will be watching you very, very closely. It is appalling that you have made this very, very dangerous change. You only need to review the statistics of mens abuse to women and children, which you clearly understand. A man is biological and You must comply with the law! You are flouting the law, in order to appease a few biological men, putting children at risk.

I’m 12 and I have a crush on an 11 Yr old girl. She is very hot. I’m in California is there any legal way to say “I wanna fkkk you”?
Mr plod. 06/12/2020 at 12:20 pm
I totally agree with the comment about, borderline paedophilia. What are you people hoping to achieve. Some of the stories...are fairy tales at best. This is a serious problem and all people are doing is titillating their sick fantasies. Shame on all of you.

Me and my boyfriend are 15 and we where going to do stuff while my mum was in work but I didn't know she would be back early and as soon as me and my boyfriend got naked my mum walked in my room and know I don't know how to feel as she told his parents which is making me not want to go his house

When I was young, around 11, I was a bad kid. I would sneak out of my house and visit someone who was 3 years older than me. We are together now, but anyways, I would visit her, and I lied to her, saying that I was also 14. After she turned 15, I asked her if she wanted to do it. I knew she would answer "No" but I thought it would be proof that "I was her age"
Anyways, I just wanted to share my expirence with this. I knew then, and I know now that it was very wrong, and shouldn't have asked her, or even been dating her.
(Don't think i'm a boy. I am bi girl lean and a girl) She is now 25, and I'm 21. She also knows that I lied to her, but after a while she understood why

- Childline
- Time to Change has a list of call lines if anyone wants someone to speak to
- NHS a list of mental health support charities to talk to/ email/ text
- NHS has information regards to abuse also

Sending care x

I am litterally tripping at the majority of the comments on this site! I thought the first couple was a sick joke, but as I scrolled, all of these comments are sick, twisted, child molesting crap! What is wrong with you people? Your going to hell in a hand bag! I'd hate to be any of you when it comes time to stand before God!

Hi, I would and will allow my kids to sleep and date whoever they want to after they turn 12 years of age. Its their business whom they choose and what age. Why as a society have we started making laws on who people can sleep with. We need to sop all the governing of our body by our government. Our body, our life, our partners.

My 11 year old daughter is dating my 22 year old nephew but she is pregnant I don’t want him to get prosecuted so I wondered if I could change the law ? Could I sue him instead my family needs more money is that legal ?
Veronica 30/11/2019 at 12:36 pm
Okay. so my boyfriend is a drug addict and he beats both me and his son, his son is 15, and i'm 37, and hes raped me on multiple occasions. I liked it but if i reported it as rape would he get in trouble and not me? By the way my boyfriend gives his son drugs when doesn't know, so this may be the reason his hormones are acting up.
Kev 27/11/2019 at 6:52 am
My 13 year old daughter as thought about taking thing to next level with her 15 year old boyfriend. Would this be against the law if he persuaded her to sleep together or she did It off her own!??
Alicia 25/10/2019 at 2:02 pm
