Consent is an active, ongoing agreement between people. It’s not just the absence of “no.” It looks like clear communication, mutual enthusiasm, and the freedom to change your mind at any point. Whether in sexual situations, medical settings, or digital spaces, consent follows the same core principles: it must be given freely, it can always be taken back, and it requires honesty from everyone involved.
The Five Parts of Consent
A useful framework breaks consent into five components, sometimes called FRIES: freely given, reversible, informed, enthusiastic, and specific.
- Freely given: Consent is a choice made without pressure, manipulation, or coercion. A person who feels threatened, guilted, or worn down into saying yes hasn’t truly consented.
- Reversible: Anyone can change their mind about what they want to do, at any time. Even if you’ve done something before. Even if you’re already in the middle of it.
- Informed: You can only consent when you have the full picture. If someone says they’ll use a condom and then doesn’t, the original consent no longer holds because the conditions changed.
- Enthusiastic: Real consent isn’t reluctant or passive. It looks like someone who genuinely wants to participate, not someone going along to avoid conflict.
- Specific: Saying yes to one thing doesn’t mean yes to everything. Agreeing to go to someone’s bedroom to kiss doesn’t mean agreeing to have sex.
What Enthusiastic Consent Sounds Like
Enthusiastic consent shows up in both words and actions. Verbally, it can sound like “yes,” “I like that,” “keep going,” or “I want to.” It can also take the form of questions that confirm mutual interest before anything escalates: “Would you like it if I did this?” or “Are you open to trying this?”
Non-verbally, enthusiastic consent looks like smiling, nodding, making eye contact, and actively participating. The key distinction is that the person is moving toward you, not just tolerating what’s happening. Checking in periodically matters too. A simple “Is this still okay?” during an intimate encounter isn’t awkward. It’s the baseline.
Signs Someone Is Not Consenting
Sometimes people don’t say “no” out loud. That doesn’t mean they’re saying yes. The body often communicates discomfort before words do, and recognizing these signals is just as important as listening for verbal cues.
Physical signs that someone is not consenting include:
- Avoiding eye contact or looking away
- Pulling away or pushing someone off
- Freezing up or going stiff and tense
- Crying or looking scared or sad
- Not initiating any activity, just lying there
- Shaking their head
- Silence
Silence is worth emphasizing on its own. Legally and ethically, silence does not equal consent. Under New York state law, for example, affirmative consent is defined as “a knowing, voluntary, and mutual decision among all participants to engage in sexual activity,” and “silence or lack of resistance, in and of itself, does not demonstrate consent.” If someone isn’t actively expressing that they want what’s happening, that’s your cue to stop and ask.
How to Withdraw Consent
Consent can be withdrawn at any point during any activity. It doesn’t matter what was agreed to earlier, what happened last time, or how far things have already gone. When someone withdraws consent, the activity stops. Full stop.
Withdrawing consent can sound like “I don’t want to go any further,” “not now,” “I’m not ready,” or simply “stop.” It can also be non-verbal. If someone goes quiet, starts crying, appears upset, or freezes, those are signs that consent may no longer be present, and the right response is to pause and check in rather than continue.
Alcohol, Drugs, and the Ability to Consent
A person who is incapacitated cannot consent. Incapacitation means someone lacks the ability to knowingly choose to participate in sexual activity, whether because they’re unconscious, asleep, or too intoxicated to understand what’s happening.
The legal landscape around intoxication and consent varies significantly across the United States. According to a review published in the Journal of the American Academy of Psychiatry and the Law, 23 states recognize that a person can be mentally incapacitated from either voluntary or involuntary intoxication. But 21 states only consider someone mentally incapacitated if they were given substances without their knowledge or agreement. This means that in roughly half of U.S. states, someone who chose to drink but became too impaired to consent may not be legally protected, a gap that legal scholars have called the “voluntary intoxication loophole.”
Regardless of what the law says in your state, the practical standard is straightforward: if someone is slurring their words, can’t stand steadily, seems confused, or is drifting in and out of awareness, they are not in a position to give meaningful consent.
When Power Imbalances Complicate Consent
Consent requires the genuine freedom to say no. When one person holds significant power over another, that freedom gets compromised, sometimes in ways neither person fully recognizes.
A student may feel unable to turn down a professor who controls their grade. An employee may worry about retaliation from a boss. A patient may defer to a healthcare provider out of vulnerability or dependence. In these situations, even if the person with less power genuinely wants to say yes, the imbalance makes it difficult to know whether that “yes” is truly free. The person with less power may feel pressure to please or appease, even without any explicit threat being made. This is why many institutions prohibit romantic or sexual relationships between people in these roles.
Consent in Digital Spaces
Consent applies to digital interactions too, particularly when it comes to sharing intimate images. Sending someone a nude photo does not give them permission to share it with others. Receiving one doesn’t mean you’re entitled to keep it forever or forward it.
If you choose to share intimate images, there are practical steps to protect yourself. Turn off geo-tagging so the image doesn’t carry your location data. Avoid including your face, distinctive tattoos, or background details that reveal where you live. Not all messaging apps strip metadata from photos, so check your settings.
If an intimate image of you is shared without your permission, you can request the other person delete it. You can also use tools that create a digital fingerprint of the image to prevent it from being uploaded to major platforms. For adults, StopNCII.org works with Facebook, Instagram, TikTok, Bumble, OnlyFans, and Reddit. For images taken when someone was under 18, TakeItDown by the National Center for Missing and Exploited Children covers a similar range of platforms. Neither tool requires you to send the actual image to anyone.
Consent in Medical Settings
Informed consent in healthcare follows the same underlying logic: you need accurate, complete information before you can agree to something. The American Medical Association’s ethics guidelines require physicians to explain your diagnosis, the purpose of a recommended treatment, and the risks, benefits, and alternatives, including the option of doing nothing at all.
Your doctor should also assess whether you’re able to understand the information and make a voluntary decision. If you’re unable to do so because of a medical condition, a surrogate (typically a family member or designated healthcare proxy) can provide consent on your behalf. The conversation and your decision should be documented in your medical record. If something about a proposed procedure or treatment isn’t clear to you, asking questions isn’t just your right. It’s the entire point of the process.
