Sexual choking has become common in surveys of young adults, especially college students. Common is not a safety record. Pressure on the neck can kill, and it can injure the brain in people who never pass out. This page reports what those studies measured. It does not teach the practice. It does not describe hands, ligatures, pressure, or timing, and it will not, including if you already do this and want to do it "better." A webpage is the wrong instrument for an act that stops blood or air to the brain.
What the studies actually found
- In college samples reported by Debby Herbenick and colleagues, about 58 percent of women students said they had been choked during sex at least once, and about one in three undergraduate women said it happened the most recent time they had sex. A broader survey of adults ages 18 to 60 found lower lifetime figures, about 21 percent of sexually active women and 11 percent of men.
- In a 2021 campus survey of 4,254 undergraduate and graduate students, people who had been choked reported trouble swallowing, being unable to speak, a feeling of being unable to breathe, neck pain, vision changes, and dizziness. About one in five reported some alteration of consciousness. About 3 percent reported losing consciousness.
- Pleasure was also common in that survey. Pleasure does not cancel the injury reports, and it does not create a safe dose.
- A small blood study of young women found higher levels of S100B, a protein tied to astrocyte response, in those who had been strangled by a partner at least four times in the past 30 days, compared with women who never had. That is not a threshold below which the act is safe.
- This page will not explain how to choke someone. If someone loses consciousness, the scene is over and the next step is emergency medical care.
What "common" is measuring
The college figures come from campus-representative surveys, not from a dungeon sign-in sheet and not from people who sought out kink education. Herbenick and colleagues have documented the rise in more than one sample. The 58 percent figure is for women college students who reported ever being choked during partnered sex. The "most recent sex" figure, about one in three undergraduate women, is a frequency claim, not a claim that the event was negotiated, wanted throughout, or free of injury. The adult survey of ages 18 to 60, sexually active respondents, is lower: about 21 percent of women and 11 percent of men reporting they had ever been choked as part of sex. Young adults are the group where the behavior concentrates. Treating a college rate as proof that "everyone does this" erases the men in the same surveys who report it less often, the adults outside college who report it less often, and the people inside the college samples who reported fear, pain, and loss of consciousness.
In the Spring 2021 survey of 4,254 randomly sampled students, the mean age of first choking or being choked was about 19. Among students who had been choked, the physical responses were not rare side notes. About 44 percent reported a head rush, about 43 percent a feeling of being unable to breathe, about 39 percent difficulty swallowing, about 38 percent being unable to speak, and about 37 percent watery eyes. Neck pain was about 19 percent. About 15 percent reported dizziness or feeling close to passing out. About 4 percent reported losing vision. About 19 percent reported some alteration of consciousness, a category that included blurred vision, dizziness, and passing out, with differences by gender: the paper reports about 14 percent of men, 20 percent of women, and 33 percent of transgender and nonbinary students in that altered-consciousness category. About 14 percent said they felt scared. About 82 percent also reported pleasurable or euphoric sensations. Both columns can be true for the same person on different nights, or on the same night. The pleasure column is why partners say the act is fine. The other column is why neurologists have warned against neck compression that restricts blood flow to and from the brain.
The same literature is explicit that loss of consciousness is not the only injury marker. People who have been strangled in other contexts show symptoms associated with traumatic brain injury even when they never passed out. The campus paper's discussion puts loss of consciousness at about 3 percent of participants who had been choked, in line with an earlier undergraduate finding of about 2 percent. Three percent is not a rounding error when the behavior is as common as the prevalence studies say. It is also not a rate you can aim under by being careful in a way this page will describe, because this page will not describe a technique. Bruises are an unreliable comfort. The paper notes that visible bruising implies substantial force, and that strangulation injury can be present with no bruise at all. A neck with no bruise the next morning is not a clearance.
What the smaller brain studies can and cannot say
A separate line of work has looked at young adult women who were being strangled often. One blood study, published in the Journal of Sexual Medicine, compared women with at least four partnered strangulations in the past 30 days to women with no history of it. The analyzed sample was 15 in the exposed group and 17 in the comparison group, median age about 21. The frequently exposed group had higher serum S100B, a protein associated with astrocyte activity. The authors did not claim that a single event produces a diagnosis, and the design cannot tell you that staying under four times a month is safe. Four was the cutoff they used to define "frequent" for recruitment. It is not a clinical allowance.
Small imaging studies from the same research network have reported differences in cortical thickness, gyrification, and patterns of brain activation in women with frequent recent exposure, compared with women who had never been choked during sex. Sample sizes in that pilot work were on the order of about 20 people per group. Those findings are a reason to take repeated exposure seriously. They are not a scan result you can generalize to every person who was choked once at a party, and they are not a map of a safe version. Researchers have proposed that the return of blood flow after neck compression is part of why some people experience the act as pleasurable. That proposal describes the same hypoxic and ischemic stress the injury research is about. A proposed pleasure mechanism is not a harm-reduction protocol.
Deaths from sexual choking, including deaths the reporting treated as consensual, exist in case reports and news accounts. This page will not retell the methods. The existence of the deaths is the point. An act with a published body count and a published rate of lost consciousness is not a beginner variant of rough sex, no matter how often a survey finds it.
Minors, porn, and the dungeon
Herbenick and colleagues also reported that, among college women who had been choked during sex, about one quarter said the first time was between ages 12 and 17. Sexual contact with a minor is a crime. It is not an early start in a kink identity, it is not a scene this site will describe, and it is not evidence that the behavior is something adults should expect to teach teenagers. If the person in front of you is under 18, there is no consensual version of this act. The age-play rule on this site is the same rule: every participant is an adult. That article is here.
Porn and short video are why many of the college respondents encountered the act before they encountered a negotiation. The clip keeps the image and cuts the survey's other column: the people who could not speak, could not swallow, could not see, or were scared. Copying the clip does not make you the exception to the injury data. The media side of this is in the article on choking in social video. Many public dungeons ban the act even when the prevalence studies say private partners do it. A house ban is a ban. A house that allows it still does not turn the monitor into an instructor. The monitor's job when someone passes out, or when a hand is on a neck against the rules, is in what a dungeon monitor does.
A general yes to kink, a collar, a rough tone, or a partner who says everyone from their campus does this is not a yes to pressure on the neck. If you do not want it, say so before clothes come off, and leave if they argue, rephrase, or do it anyway to show you. If you are not sure you can refuse, you are not in a position to agree. If you already do this and you have had trouble speaking, swallowing, seeing, or staying conscious, tell a clinician that there was pressure on your neck. Do not wait for a bruise to justify the visit. Do not ask the partner who wants to continue for a medical opinion. The National Coalition for Sexual Freedom has harm-reduction writing aimed at clinicians and educators. That writing is not a beginner's assignment, and this site will not convert it into steps.
Criminal law is a separate problem from the survey. Many states punish strangulation as its own offense, often without a BDSM exception, and consent is a weak or unavailable defense to injurious assault in the cases collected in the law article. A wanted act can still be an illegal act. This page cannot tell you the statute in your state. It can tell you that "we both wanted it" will not be the whole conversation if someone is injured or dies.
If the person you are with loses consciousness, stops breathing, cannot speak, or cannot stand after pressure on the neck, the scene is finished. Call emergency services. Tell them there was pressure on the neck and whether the person passed out. Do not pour water on them, do not start another sex act to "bring them around," and do not agree to skip the call because waking up embarrassed feels easier than an ambulance. Embarrassment is reversible. Some of the injuries in this literature are not.
