What Is the Eiffel Tower in Sex? The Slang Term Explained
What the Eiffel Tower means in sex slang, where the term came from, and how consent, STI protection and aftercare work when three or more people are involved.

Table of Contents
The Eiffel Tower in sex is slang for a group arrangement, not a move for couples. It describes three or more people, with one person in the middle and a partner at each end. The two outer partners join hands above the middle person, and that shape gives the term its name.
So if you heard it in a meme, a song lyric or a group chat, the short answer is that it means a threesome in a specific layout. The more useful question is what any group encounter asks of the people in it.
This guide explains the term in plain, non-graphic language. Then it covers what matters more than the shape: consent from everyone, an honest talk beforehand, lowering STI risk with several partners, and handling jealousy and aftercare.
What the Eiffel Tower means in sex slang
The short definition
Every page that ranks for this term agrees on one meaning. WebMD, whose page is medically reviewed, calls it a position for three or more people arranged in a formation that looks like the Eiffel Tower. Urban Dictionary, the crowd-sourced slang site, defines it the same way and lists it as a kind of threesome.
This sets it apart from most named sex positions, which describe two people. You cannot do the Eiffel Tower as a couple. If someone uses the phrase about a couple, they are probably joking or have the term confused with something else.
The people involved can be any mix of genders. Slang definitions often assume two men and one woman, but that is a stereotype of the joke, and nothing in the term itself requires it. WebMD also notes that more than three people can be involved.
Why it is named after a landmark
The name is visual. One person sits in the middle on their hands and knees, forming the base. A partner is at each end, and the two outer partners touch or clasp hands above the middle person.
Seen from the side, the two outer people and their raised arms make a rough triangle with a peak. That peak is the “tower.” The hand-clasp is often described as a high-five, which is part of why the term reads as a joke as much as a description.
Eiffel Tower vs spit roast and other terms
People often mix this term up with “spit roast,” another slang phrase for a three-person arrangement. According to WebMD, the general layout is the same. The difference is only the hand-clasp: in the Eiffel Tower the outer partners join hands, and in the other they do not.
You may also see the term used as a verb. Urban Dictionary lists forms such as “Eiffel towered” and “Eiffel towering”. In one example on that page, someone is “Eiffel towered,” so the verb can describe what happened to a person. Because it comes from joke slang, it can sound crude when repeated, which is worth knowing before you use it.
Other everyday words cover the same ground more plainly. WebMD defines a threesome as three people having sex together. Some sources keep “group sex” for four or more people, but in everyday use it often covers threesomes too. In this guide, “threesome” means three people, and “group sex” is the broader term for sex with more than two people.
How a niche slang term went mainstream
From crowd-sourced dictionaries to pop concerts
The term is older than its recent fame. The top Urban Dictionary entry for it is dated February 21, 2003, and later entries keep adding variations. For years it lived mostly in jokes, forums and slang lists rather than in mainstream conversation.
The term got a much bigger audience in March 2025. During a Paris concert, singer Sabrina Carpenter staged a joking reference to the city, using two male dancers to mimic the arrangement. The moment went viral, and the term was suddenly being debated in public.
The moment also started an argument. A viral post called the position degrading to women. Others answered that something adults choose freely and enjoy is not degrading just because men are present. Both sides were really arguing about consent and choice, which is where this guide spends most of its time.
Why sex slang spreads so fast
Short, picture-like names travel well online. A phrase like “Eiffel Tower” is easy to remember, easy to joke about, and safe to post because it sounds harmless.
Some observers of online language think this happens faster now. An informal student project published on a UCLA linguistics blog argued that when millions of people watch the same content at once, slang changes faster than before. It also noted that slang works as a marker of identity and group belonging. That helps explain why people pick up a joke term to show they are in on it.
Speed has a cost. A meme name hides the people behind it. It says nothing about whether everyone wanted to be there, whether they used protection, or how they felt afterwards. Those details decide whether an experience is good or harmful, so they are the focus of the rest of this article.
How common is group sex?
Fantasy is far more common than experience
The best-known numbers here are about threesomes, the smallest form of group sex. A threesome is a common fantasy and a much less common reality. One survey cited by WebMD found that about 95% of men and 87% of women have fantasized about a threesome. Yet another study found that only 10% of women and 18% of men had actually had one.
Among people who have tried it, most did not make it a habit. Over 80% said it was a one-time experience, mainly to satisfy curiosity. People who had a threesome tended to remember it positively, especially when a committed partner was part of it.
The gap between fantasy and action is worth noticing. Wanting to imagine something is normal, and it does not create any duty to act on it. Plenty of people enjoy the idea and decide the reality is not for them.
Where it fits in consensual non-monogamy
A threesome sits inside a wider category called consensual non-monogamy, or CNM. The Kinsey Institute defines CNM as any relationship where all partners agree that each may have other romantic or sexual partners. It covers open relationships, swinging and polyamory.
CNM is more common than many people assume. Two national samples of single US adults found that 21.9 percent and 21.2 percent had been in a CNM relationship at some point. Kinsey Institute research also found that 1 in 9 single Americans have been in a polyamorous relationship.
A single threesome is not the same as an open relationship, though. Some couples try group sex once and stay monogamous otherwise. Others build ongoing agreements. What all these setups share is the word “consensual,” and that word carries the rest of this guide.
Consent when three or more people are involved
Everyone says yes, separately
In any group encounter, consent has to come from every single person. WebMD puts it plainly: consent is an ongoing process, and it involves all three participants. No one should be pressured to take part.
This matters most when a couple invites a third person. The couple has already talked for weeks, while the newcomer may be meeting them for the first time. Two people agreeing together can feel like a majority vote, but consent does not work by majority. Each person’s yes has to be their own.
Pressure can also run inside the couple. Agreeing to a threesome mainly to please a partner can leave someone feeling guilty or resentful later. Consent given out of fear, or under pressure from someone with power over you, is not real consent.
Consent can change at any moment
A yes at the start of the evening is not a yes to everything that follows. Consent means everyone clearly agrees to what is happening, and if the activity changes, consent must be given again. It is ongoing and can be withdrawn at any time.
With three or more people, check-ins get harder because attention is split. Watch for signs that someone wants to stop, such as tense body language, avoiding eye contact, pulling away, or saying “wait”. Silence is not a yes either.
Any member of a trio has the right to stop at any time. Agreeing once does not oblige anyone to do it again.
Alcohol, drugs and the ability to consent
People sometimes drink to calm nerves before a first threesome. That makes consent harder to judge. Alcohol and drugs impair judgment and communication, so it gets harder both to give consent and to know whether you have it.
Brown University’s health team draws a clear line. Someone who is intoxicated may still be able to consent, but someone who is incapacitated cannot. Signs of incapacitation include being unable to speak coherently, confusion about basic facts, and being unable to walk without help.
If you are unsure whether someone is too impaired, assume they cannot consent. The safest plan is to have the important conversations sober, before anyone has had a drink.
Talking it through before anything happens
Boundaries and limits
Most hurt feelings after group sex come from things nobody said out loud. WebMD calls talking it through the most important step for avoiding problems. The more openly people discuss their desires, likes and dislikes, the less likely they are to end up disappointed.
Start with hard limits. Each person names what is off the table for them, physically or emotionally. For one person it might be kissing. For another, it might be watching their partner with someone else.
When a couple invites a third person, the conversation should include that person as an equal. Ask what they want and what they will not do, rather than presenting a finished plan. Settle practical points too, such as where it will happen, and whether the third person stays the night or goes home. A plan for what to do if someone feels left out is also worth agreeing in advance.
Stop signals and check-ins
Agree on a safe word before anything starts. It should be a word or phrase that anyone can say to stop, change what is happening, or leave. Some couples choose a second, private signal for when one of them is uneasy about what is happening between their partner and the third person.
A safe word is a backstop, not a substitute for checking in. Short check-in questions during the encounter help. Ask whether things still feel good, or whether anyone wants a break. Communication does not end when things begin, and it should continue afterwards too.
Agreeing on the safer-sex plan
Settle protection before anyone undresses. WebMD suggests that all three people discuss their STI status ahead of time, along with how sex will be kept safe and what birth control will be used. Decide whether condoms or other barriers will be used, how often everyone tests, and how test results will be shared.
Then agree on what happens if someone will not share a result or will not use a barrier. The simplest rule is that the encounter does not happen. A plan that one person can quietly ignore is not really a plan.
STI risk with multiple partners
Why more partners mean more exposure
Every extra partner adds another person’s sexual history to the room. With three people, an infection does not have to pass only between the couple and the newcomer. It can move from any one person to either of the others, and between body sites on the same person.
How much risk group sex adds depends on who is involved. WebMD reports no scientific evidence that STI risk is higher in mixed-gender threesomes. The same guide notes that HIV transmission risk is considerably higher in same-sex encounters involving more than 2 men. The Kinsey Institute adds that polyamorous people, despite having more partners, tend to use safer-sex strategies and report similar STI rates to monogamous people. In other words, the habits people bring matter more than the label.
A fresh condom for every partner
Condoms lower the risk of every STI when used correctly every time. In group sex, the common mistake is reusing one condom between partners. WebMD’s advice is to use a different condom or latex barrier for each partner, and new ones when switching back and forth.
Research shows why this rule matters. A 2022 study from the Melbourne Sexual Health Centre looked at group sex reported by female sex workers attending one Melbourne clinic. Most said their male partners used condoms, but one in six of those men did not change condoms between women during vaginal sex. That is one specific group, not all group sex, but the mistake it describes is easy to make anywhere. The authors warn this can increase STI transmission, and suggest a new condom when switching between oral, vaginal and anal sex too. The same applies to shared sex toys.
Condoms do not cover everything. Herpes and HPV can pass through skin contact even when a condom is used.
Testing, window periods and prevention
Testing before a new partner is the usual advice. Action Canada suggests testing every 3-6 months if you or your partners have new partners often. Many STIs have no symptoms, so testing is the only way to know.
A recent negative test has limits, because of window periods. A window period is the time after contact before a test gives an accurate result. Chlamydia tests are most accurate after 2 weeks, while syphilis has a window of 3-4 weeks. For HIV, 95% of antibody tests are accurate after 4-5 weeks, and the most accurate result can take up to 3 months. So a clean result only covers contact from before that window.
Two medical tools add protection. PrEP, a daily pill or regular shot, reduces the risk of getting HIV from sex by about 99% when taken as prescribed. It does not protect against other STIs. The HPV vaccine prevents the most common STI and is recommended for everyone through age 26 who has not had it.
Physical comfort and the person in the middle
The physical risks are mostly about strain, and they fall hardest on the person in the middle. WebMD lists neck and back strain and physical exhaustion as risks of this arrangement. Holding one posture on hands and knees can also hurt the wrists and knees.
Simple steps help. WebMD suggests pillows or rolled towels as cushioning, and keeping the hips level and the spine straight. The hand-clasp that gives the term its name does not have to be held the whole time; WebMD says that is entirely up to the people involved.
The person in the middle also has the least freedom to move or speak. That makes the stop signal especially important for them. Agree on a non-verbal signal, such as tapping a hand twice, so they can stop things even when talking is awkward. If anything hurts, stop and change position.
Jealousy, feelings and aftercare
Jealousy is normal and manageable
Jealousy is one of the most common reasons a threesome goes badly. WebMD warns that it can bring up jealousy and insecurity, especially when boundaries and expectations were not discussed beforehand. Feeling a pang of it does not mean you did something wrong.
Research on consensually non-monogamous people helps explain who struggles most. A study of 255 people, reported by PsyPost, found that jealousy and attachment anxiety were the strongest predictors of a negative reaction to a partner’s new connection. Attachment anxiety means feeling unsure of your place in the relationship.
The same study points to what helps. People who knew more about their partner’s other connection, and who liked the other person, felt more of what researchers call compersion. Compersion means feeling happy that your partner is enjoying someone else. For a threesome, that suggests a simple step: name the jealousy you expect before the night, and agree on what each of you needs if it shows up.
Aftercare for all three people
Aftercare is the time after sex when people reconnect, through cuddling, talking or just checking in. Research summarized by sex researcher Justin Lehmiller links this kind of post-sex affection to greater sexual and relationship satisfaction. In one survey of 335 adults in relationships, more time spent on it went with higher sexual satisfaction.
Those studies looked at couples, but the principle carries over. The third person is often the one most likely to be left out afterwards. A good plan includes them: a few minutes together, a glass of water, and a message the next day to ask how they are doing.
The couple should also check in with each other, both that night and a few days later. Feelings can surface late, and a calm talk a couple of days later is easier than an argument in the middle of the night.
It will not fix a struggling relationship
A threesome tends to magnify whatever is already in a relationship. If the relationship is not strong to begin with, it may do more harm than good. Sex can also lead to emotional attachment that nobody planned for.
Thinking about group sex to save a relationship or keep a partner happy? Pause first. Talking to a couples therapist or a certified sex therapist first is a sensible step. Look for one who is open to non-monogamy. In one study, nearly half of people in CNM relationships who sought therapy looked for a therapist who affirmed their relationship style.
Frequently asked questions
What does the Eiffel Tower mean in slang?
In sexual slang, the Eiffel Tower is a group arrangement for three or more people. One person is in the middle, with a partner at each end, and the two outer partners join hands above them. The raised arms make a tower-like peak, which is where the name comes from. Outside of sex, the phrase still just means the landmark in Paris.
What does it mean to be “Eiffel Towered”?
“Eiffel Towered” uses the slang term as a verb, and Urban Dictionary lists it among the term’s variations. In one listed example, the verb describes something done to a person. Because it comes from joke slang, it can come across as crude or insulting. Use the plain words if you need to talk about it seriously.
Is the Eiffel Tower a couple’s position?
No. It needs at least three people, which is why WebMD describes it as a position for three or more. Any two-person position with a similar name is a different thing. If a partner suggests it, they are suggesting a threesome, and that calls for a real conversation about consent and safety first.
Is group sex safe?
Group sex can be lower-risk when everyone consents, uses protection and tests regularly, but it is never risk-free. Use a fresh condom or barrier for each partner and change it when switching. Get tested before new partners and remember window periods. If HIV is a concern, PrEP reduces the risk from sex by about 99% when taken as prescribed.
Do you have to tell a partner about an STI before group sex?
Yes, in practice. Each person can only give real consent if they know the risks involved. WebMD advises that everyone discuss their STI status before a threesome. Many STIs cause no symptoms, so a recent test result is more useful than a guess. If someone will not share, the others can decide not to go ahead.
The bottom line
The Eiffel Tower is slang for a three-person sexual arrangement, named for the shape the two outer partners make when they join hands. It is not a position for couples, and the joke behind the name says nothing about the people involved.
What makes any group encounter go well has little to do with the layout. Three things matter more. First, everyone says yes for themselves, sober, and can stop at any time. Second, the group agrees a safer-sex plan in advance, with fresh barriers for each partner and recent tests. Third, there is time afterwards to check in with every person, including the one who goes home.
If you are curious, start with a conversation rather than a plan. If that conversation feels hard, that is useful information too.
