What is sexual consent? It is an agreement to take part in something sexual, and it only counts when it is free, clear and current. That sounds simple, and yet people still find it hard to say, to hear and to ask for. This guide explains consent in plain words. It covers what consent is, five qualities that sexual health educators use to describe it, how to ask for it, give it and take it back, and what cannot count as consent. It also shows how the same ideas apply in kink, in couples and at work. It is aimed at adults, and the language is never explicit. It is general information, not legal advice, because rules about consent differ from one place to another.
What consent is
Planned Parenthood, a sexual health organisation, describes consent as actively agreeing to be sexual with someone, and it states that sexual activity without consent is sexual assault or rape. The World Health Organization points the same way when it says that sexual health calls for the possibility of sexual experiences free of coercion, discrimination and violence. Consent is not a hurdle to clear once. It is a conversation that runs for as long as anything is happening.
Five qualities of consent
Planned Parenthood sums consent up with five words. They make a useful test for any yes.
- Freely given
- A choice made without pressure or manipulation, and not under the influence of drugs or alcohol.
- Reversible
- Anyone can change their mind at any time, even after saying yes before, and even in the middle of something.
- Informed
- A yes needs the full story. If someone says they will use protection and then does not, there was no full consent.
- Enthusiastic
- A person should only do what they want to do, not what they feel is expected of them.
- Specific
- A yes to one thing is not a yes to another. Agreeing to a kiss is not agreeing to more.

Asking for consent
Asking does not spoil the mood. It is part of paying attention. A good question is open, specific and easy to answer with a no.
Questions that make it easy to say no
- “Would you like this?”
- “How does that feel?”
- “Do you want to keep going, or take a break?”
- “Is there anything you would rather we did not do?”
Listen to the answer, and to what sits behind it. Hesitation, silence or going still are not a yes. Planned Parenthood is clear that silence is not consent, and that consent is never implied by someone’s past behaviour, clothes or whereabouts. If you are not sure, stop and ask in words. A maybe is not a yes either.
Giving or refusing consent
You are allowed to say yes to one thing and no to another, yes now and no in a minute, yes today and no tomorrow. You never owe a reason, and you never owe a yes because of what happened before. Sexual boundaries offers words for saying no kindly, and a short sentence is always enough.
Taking consent back
Anyone can change their mind, whatever was said earlier and however far things have gone. The person who hears it has one job: to stop at once, without asking for a reason and without sulking. A safeword is one way of making this easy when words are hard to find, and safewords explains how it works. Withdrawing consent says nothing bad about anyone. It is information, and a respectful person welcomes it.
What cannot count as consent
Not consent
- Silence, or going along because it feels impossible to say no.
- A yes given under pressure, persuasion or threats.
- A yes given by someone who is drunk, high, asleep or passed out.
- A yes based on something untrue, such as a false promise.
- Past behaviour, clothes, or a place someone chose to go.
- Last month’s yes, or the yes of a long relationship, applied to today.
Planned Parenthood adds that couples who have had sex before, even ones together for a long time, still need consent each time. Rules about who can consent, and about age, are set by law and differ from one place to another, so check the rules where you live.
Consent in kink
Kink communities place consent at the centre. The National Coalition for Sexual Freedom notes that “safe, sane and consensual” was coined in 1983, that many people now prefer “risk aware consensual kink”, and that consent remains the foundation either way. GoodTherapy, a therapy directory, states that kink practices involve consenting adults by definition, and that rape, abuse and assault are not kink. It lists practical ways to protect consent: enthusiastic agreement from everyone, a full talk about boundaries and hard limits beforehand, a safeword and regular aftercare.
A negotiation checklist, aftercare and kink for beginners cover each of these steps.
Consent in couples
Being together does not replace asking. Habit can make questions feel unnecessary, and that is when a small check matters most. Talking about what each person likes, and what they do not, keeps consent alive between moments. Talking about desire offers wording, and what sexual desire is explains why wanting and agreeing are different things.
Consent at work
Consent is not only about sex. It also covers what you agree to create, who may photograph or film you, where images may appear and how long they stay online, and what is said in your name. You can say no to a type of content, to a shoot or to a message, and a subscription never buys more than the content you chose to offer. A fair agency asks first, writes your limits down and respects them.
Rope photography shows what two separate yeses look like when a camera is involved, the first month describes how limits are set with an agency, and sexual boundaries includes a section on boundaries in content.
If your consent was not respected
If someone ignored a no, or acted without a yes, it is not your fault. You can tell a person you trust, keep any messages and look for a local support service, which can listen and explain your options. If you are in danger, call your local emergency number. Stalking and doxxing and leaks and reposting cover situations that involve images or threats online.
Questions about consent
Is silence consent?
No. Planned Parenthood says so plainly. If someone goes quiet, stop and ask.
Can I change my mind after saying yes?
Yes, at any moment, including after you have started and even if you said yes before.
Does a yes to one thing mean a yes to everything?
No. Each thing needs its own agreement, and a yes to one is not a yes to the next.
Can someone consent after drinking?
Planned Parenthood says that people who are drunk, high or passed out cannot consent. When in doubt, wait.
Does being in a relationship change anything?
No. Couples still need consent each time, however long they have been together.
