Sex and consent

Whether you're thinking about sex for the first time, feeling unsure, or just curious – it’s completely normal to have questions about sex. You might feel awkward talking about it – especially if you’ve been told it’s embarrassing – but there’s nothing wrong with being curious or wanting to talk things through.

You might be wondering:

  • What actually counts as sex?
  • How do I know if I'm ready?
  • Should I be having sex if other people are?
  • What does consent really mean?
  • How do I stay safe?
  • What’s contraception and how do I get it?
  • Is masturbation okay?

Whatever you’re thinking, there’s no rush to figure everything out. You have the right to take your time, get informed, and make decisions that feel right for you.

What counts as sex?

Sex can mean different things to different people. It might be:

  • Kissing, hugging or touching in a sexual way.

  • Watching or sharing something sexual.

  • Oral sex (using your mouth).

  • Penetrative sex (using a penis, fingers, or toy/object inside the vagina or bum).

  • Vaginal sex (penetrative sex in the vagina).

  • Anal sex (penetrative sex in the bum).

  • Masturbation (touching your own body to make yourself feel good).

What matters most is that everyone involved is comfortable and wants to do it. Just because something feels intimate or sexual doesn’t mean you have to do it – and just because someone else is doing it doesn’t mean you should too.

Masturbation is when you touch your body and genitals because it feels good. It’s completely natural, and anyone can do it – whatever your gender.

You might be wondering whether it’s something you should do. But there are no rules about this – it’s your choice.

If you’re feeling unsure, here are a few things to know:

  • Some people do it and some don’t. Both are okay.
  • Most people do it on their own. Some might do it with a partner. It’s never okay to do it in public.
  • There’s no right way to do it or right amount.
  • People start doing it at different ages, and that’s okay.
  • Some people might feel unsure about it because of their faith or beliefs – and that’s okay too.

Whatever you choose, it’s personal. You’re allowed to make the decisions that feel right for you.

What is consent?

Consent means freely agreeing to do something. It’s about saying “yes” because you genuinely want to – not because you’re being pressured, feel scared, or you’re unsure.

You can give consent by:

  • saying yes clearly and confidently
  • showing you’re comfortable through body language and actions

But just because someone doesn’t say “no”, it doesn’t mean they’re saying “yes.” You should always check in with the other person and pay attention to how they’re reacting.

In the UK, the legal age of consent is 16. This means it’s against the law for anyone to have sex with someone under 16 – even if they agree to it. And if someone is under 13, the law says they can’t consent to sex at all.

Consent must be:

  • given freely, without pressure or guilt
  • informed – you know what you’re agreeing to
  • ongoing – it can be changed or taken back at any time
  • specific – saying yes to one thing doesn’t mean you’re saying yes to everything

You can’t assume that someone is consenting – you need to check. Things like body language and what someone says can be helpful signs, but they aren’t always enough on their own. Even if someone seems okay on the outside, they might still feel unsure. That’s why it’s always best to ask.

Signs that someone might be giving consent:

  • positive body language (smiling, relaxed, enthusiastic)
  • clear communication (they’re saying “yes” without pressure and seem comfortable)
  • changes in how they’re feeling – just because someone was into it earlier doesn’t mean they still are

Signs someone isn’t giving consent:

  • they seem quiet, nervous or unsure
  • they’re not responding or freezing up
  • they say “maybe,” “I don’t know,” or “I guess so”
  • they pull away, go still or change the subject
  • they say they don’t want to

If someone is drunk, high, asleep, or unable to understand what’s going on – they can’t give consent.

If you're ever unsure – stop. Ask how they’re feeling and be ready to listen. Consent isn’t a one-time thing – you need to keep checking in and respect any decision to stop.

How do I know if I'm ready?

There’s no 'right' age or time to have sex. It’s a personal choice, and you don’t have to do anything you’re not comfortable with. If other people your age are having sex, you might feel like you should be too. But everyone feels ready at different times and just because other people are doing it doesn’t mean you have to as well.

Here are some questions to ask yourself to figure out how you feel:

  • Do I feel comfortable to do sexual things with someone?

  • Am I choosing this because I genuinely want to, or because I feel pressured, like I should, or worried about what will happen if I don’t?

  • Am I doing this just to make someone else happy or do I want it for myself?

  • Do I feel safe to talk to my partner about sex, including what I do and don’t want?

  • Do I know about contraception, where to get it and how to use it?

  • Have I thought about what I’d do if something didn’t go to plan?

  • Do I know how to say no if I change my mind or feel uncomfortable?

If you’re feeling unsure, that’s a good sign to wait. There’s no deadline and saying no now doesn’t mean you’re saying no forever.

Your faith or religious beliefs can play a big part in how you think about sex and when you feel ready. Different religions have different views. Some see sex as something sacred that should happen only within marriage, while others have specific rules about when and how it’s okay.

Because of this, you might feel extra pressure or uncertainty about having sex, or you might decide to wait until it fits with your values and what feels right for you. That’s completely okay. Everyone’s journey is personal, and respecting your own beliefs and feelings is an important part of making decisions about sex.

If you ever feel confused or conflicted, talk to someone you trust – like a family member, religious leader, or teacher. They can help you explore what feels right for you.

Contraception and staying safe

Two girls wearing black jackets are talking while standing against a wall decorated with blue, purple and green graffiti patterns.

If you're thinking about having sex or being sexually active, it's important to think about using contraception to protect both you and your partner. Contraception helps to prevent pregnancy, and some types also help protect you from sexually transmitted infections (STIs).

You can get most types of contraception for free from:

A doctor or nurse can talk you through your options and help you find something that feels right for you.

Types of contraception

Below are some of the most common types of contraception. Some of these, like the pill or implant, are mainly for people who can get pregnant. Others, like condoms and dental dams, can be used by anyone.

If you’re unsure which type of contraception is right for you, use Brook’s contraception tool to find out what’s best for you.

Worn on a penis (external) or placed inside a vagina (internal), they help prevent both pregnancy and STIs. They can only be used once.

A tablet you take every day to prevent pregnancy. There are different types, and some people find it helps with things like period pain or acne.

A small rod placed under your skin that slowly releases hormones to stop pregnancy. It lasts for up to three years

Given every few weeks to stop pregnancy.

A small device placed inside your womb. It can last between five and ten years depending on the type.

A thin sheet used during oral sex to help prevent STIs.

A pill or device used after unprotected sex to prevent pregnancy. The sooner you use it, the better it works.

What if something goes wrong during sex?

Sometimes, things don’t go to plan. A condom might break, you might forget to take the pill, or you might not have used contraception at all. That’s okay – there is help available.

You can:

  • get emergency contraception as soon as possible from a doctor, sexual health clinic, pharmacy, or online pharmacy like Superdrug or Boots
  • talk to a nurse or doctor about what to do next
  • get tested for STIs at a sexual health clinic
  • speak to someone you trust or contact Childline for support

Talking about contraception with someone

If you're planning to have sex, it’s important to talk about contraception with the other person first. That includes:

  • what protection you’ll use
  • what you’re both comfortable with
  • how to stay safe from STIs
  • what to do if something goes wrong, like a condom splitting

It might feel awkward at first, but talking about it helps make sure you both feel safe, respected and in control. You both have the right to set boundaries and say no to anything you're not comfortable with – including sex without protection.
