The Definitive Glossary of Swinger and Sex Terminology

Couple Looking Up Sex Terms

Navigating the world of swinging involves more than just an open mind and a sense of adventure; it also requires a specific vocabulary to ensure you're communicating clearly with like-minded individuals. Whether you're a seasoned couple or a newcomer to the lifestyle, understanding the language can help you connect with others, express your interests and boundaries, and avoid misunderstandings or uncomfortable situations.

The lifestyle has its own unique set of terms, jargon, and acronyms that can seem like a foreign language at first. And while many of these terms are specific to swinging, others are used more broadly throughout the world of consensual non-monogamy and adult relationships. They cover everything from types of people and relationships ("unicorns," "hotwives," etc.) to activities and preferences ("soft swap," "full swap") and the spaces and settings where people meet and socialize, such as "play areas" at adults-only events and resorts.

This definitive glossary aims to demystify the language, offering clear and concise definitions of the terms you're most likely to encounter. Whether you're exploring swinging for the first time, looking to better understand the terminology, or simply curious about a word you've come across, this guide will help you navigate the language with greater confidence. Armed with this knowledge, you'll be better equipped to communicate, explore, and enjoy your experiences in the lifestyle.

AFTERCARE

The care and attention given after an intense scene or play session. This can include physical comfort (water, blankets, treating marks), emotional check-ins, or simply quiet cuddling to ground everyone back to reality.

BAREBACK

Slang for sexual intercourse without using a condom.

BIG DICK ENERGY (BDE)

The phrase or acronym BDE refers to a confident, laid-back kind of charisma that suggests someone is self-assured in (and out of) the bedroom—without being cocky. The term went mainstream after Kim Kardashian used it on The Kardashians in 2022 to explain her initial attraction to Pete Davidson, joking that she “heard about this BDE” and wanted to see what the hype was about.

BDSM

An acronym that stands for Bondage, Discipline, Dominance, Submission, Sadism, and Masochism. It's a broad range of sexual practices involving power dynamics, role-playing, and various types of restraint or sensory stimulation.

BISEXUAL

A person who is sexually attracted to or sexually active with partners of both sexes, male and female.

BI-CURIOUS

A male or female who is interested in trying same-sex activities.

BULL

In the context of a "cuckold" relationship, a bull is the man who engages in sexual activities with a "hotwife," while her husband watches or is aware. The bull is often more sexually dominant and may play into the humiliation or submissiveness of the husband.

BUSSY

A blend of “boy” and “pussy,” bussy is a slang term for a man’s anus. It’s commonly used in queer culture, especially among effeminate bottoms (those who are the receptive partner in anal sex).

CATFISHING

A sly trick in the swinging world, where someone spins a fake persona of a couple, to lure you in with flirty messages and eye-catching photos. We see it more and more on online dating sites. They promise a fun, hot, connection, but, surprise—they're not who they say they are. In the lifestyle, honesty is key, so stay sharp! What you see isn’t always what you’re going to get.

CHOREPLAY

When a woman gets turned on by watching her husband, boyfriend, or partner tackle everyday chores. The idea is simple: doing chores thoughtfully—or even downright sexy—can heat things up faster than lingerie. Nothing says foreplay quite like unloading the dishwasher without being asked.

CLOSED DOOR/CLOSED SWINGING

This involves swapping partners but engaging in sexual activities in separate spaces or rooms. It provides a level of privacy and can be a good option for couples who are new to swinging or prefer not to witness their partner with someone else.

CLOSED-GROUP SWINGING

Closed-group swinging is a form of swinging that involves participants having multiple sexual partners who are all within a specific group of people. A common example of closed-group swinging is when couples who are friends regularly switch partners but don’t typically swing with others.

COMPERSION

A term often used within polyamorous and swinging communities, compersion describes the joy one feels when one partner experiences pleasure or happiness with another person. It's essentially the opposite of jealousy.

CONSENT

An explicit agreement by all parties involved to engage in a particular sexual activity. For swinging and BDSM communities, consent is paramount and usually involves ongoing communication to ensure everyone is comfortable

CUCKOLD

This refers to a man who takes pleasure in watching his wife or partner engage in sexual activity with another man. The emotional elements often play a significant role, including aspects of humiliation, submission, or the enjoyment of the wife's pleasure (sometimes referred to as 'compersion').

CUCKQUEAN/CUCKQUEEN

The female counterpart to a cuckold: a woman who derives pleasure from watching her male partner engage in sexual activity with another woman. Like the male version, it often involves elements of erotic humiliation, submission, or compersion.

CUDDLE PUDDLE

A cuddle puddle is a cozy pile of people—mixed sexes, all snuggled up and maybe doing a bit of heavy petting. Usually, it’s a clothes-on affair, though sometimes things get a little more… unbuttoned. It’s not an orgy; this is more about warmth and trust than wild passion. Often it’s just friends or loved ones relaxing in a big, affectionate heap, expressing closeness without always crossing into the sexual.

DEAD BEDROOM

A long-term relationship where sexual activity has significantly declined or stopped entirely. Often cited as the catalyst that leads couples to explore opening their relationship or entering the lifestyle to reconnect or find what's missing.

DOMINANT

A sexual partner in control of a willing submissive partner.

DRDP

An acronym meaning "different room, different partner."

DTF

The acronym stands for “Down to F**k! Some couples just put it out there to convey that this is what they want to do, plain and simple. Don’t waste their time with idle chit-chat because they want to get the party started. Now!

ETHICAL NON-MONOGAMY/CONSENSUAL NON-MONOGAMY

A broad umbrella term for someone who has any type of sexual or romantic relationship with more than one person without keeping it a secret from any of them. The degree to which they are forthright about the details with each of their partners (in terms of the identity, gender, sexual activity, or length of relationship) is not of concern – just the general understanding that each partner consents to a relationship with someone who is not being exclusive in every way to them.

EXHIBITIONISM

The desire to be watched by others while engaging in sexual activities. Exhibitionists derive pleasure from being observed, and this is often accommodated in the swinging and BDSM communities where consent is a key factor.

FETISH

Sexual arousal and pleasure through the use of non-sexual objects, actions, or non-genital anatomy.

FLAKE

The classic disappearing act! In the swinging scene, a flake is someone who vanishes after making plans, leaving you hanging. After lots of back-and-forth, sexy messages, and heightened anticipation, it’s a real buzzkill to get that last-minute “can’t make it” text just before a meet-up. Often, flakes are folks you connect with on apps who don’t follow through, sometimes because one partner gets cold feet or wasn’t fully on board from the start.

FLUID BONDING

The practice of agreeing to exchange bodily fluids like semen and vaginal fluids with specific partners without using barriers. This requires trust, regular STI testing, and clear communication about boundaries and exclusivity. Unlike bareback, which often describes casual unprotected sex, fluid bonding is a deliberate, ongoing agreement with chosen partners.

FMF

The acronym – along with FFM – describes the gender composition of threesomes. FMF stands for Female-Male-Female while FFM is Female-Female-Male. The difference is slight and many people use them interchangeably. The order of the letters usually indicates the interaction focus, and whether the females are bi-sexual. e.g., in FMF, the male is typically the center of attention.

A foursome – when not in relation to a group of four golfers – refers to group sex between four people of any combination of sex or gender. All four may be single, or the situation may involve two couples that identify as swingers.

GANG BANG

A gang bang is a situation in which several people engage in physical sexual activity with one specific individual sequentially or at the same time. A common scenario is a group of men having sex with one woman.

GROUP SEX

Sexual activity between three or more people, in recent times, it’s replaced the somewhat antiquated term, orgy.

HALL PASS

HETROFLEXIBLE

Someone who’s mostly straight… but not all the way straight. Think of it as living on the spectrum between heterosexual and bisexual: primarily attracted to the opposite sex, but open to same-sex experiences now and then—often depending on the situation (or the company). Heteroflexibility is considered a subcategory of bisexuality: heteroflexible folks lean straight, while bisexuals experience attraction to both men and women more evenly.

HOMOFLEXIBLE

Someone who identifies as primarily gay or lesbian but occasionally open to opposite-sex encounters depending on the person or situation. The mirror image of heteroflexible.

HOTWIFE/HOTWIFING

A consensual kink dynamic in which a husband (or primary male partner) takes pleasure in his wife (or female partner) having sex with other men. The woman is typically given the freedom—and often encouragement—to explore these encounters. The husband may or may not be present and may derive pleasure through voyeurism, compersion, or elements of cuckolding.

Popular in 1970s, the "key party" became a phenomenon among swinging couples. Interest piqued again when it was made a part of the 1997 movie, The Ice Storm with Kevin Klein and Sigourney Weaver.

KINK

In human sexuality, kinkiness (or kinky), is a colloquial term used to describe unconventional sexual concepts or practices. The term derives from the idea of a “bend” (a “kink”) in one’s sexual behavior, to contrast such behavior with “straight” or “vanilla” sexual conventions and proclivities. The term “kink” has been claimed by some who practice sexual fetishism as a term or synonym for their practices.

MFM

The acronym – along with MMF – describes the gender composition of threesomes. MFM stands for Male-Female-Male while MMF is Male-Male-Female.

ORGY

Classically considered to be group sex with several partners in somewhat of a party-like scenario. With its origin in the Greek and Roman sex parties that would last for days, where people only paused to eat and sleep, it hints at something a bit out of control, wild, and over the top.

PANSEXUAL

Attraction to people of any gender—or simply put, attraction that doesn’t care about gender at all. The “pan” comes from the Greek for “all,” which sums it up nicely. Pansexuality isn’t “better” or more inclusive than bisexuality—it’s just a different way of describing orientation.

In short, trisexuality is about having three “lanes of attraction” on the multisexual spectrum.

UNICORN

In swinging terminology, a unicorn is a single, usually bisexual, female who is interested in meeting and possibly joining a couple. Unicorns are relatively rare in the swinging community, which is why they're referred to as mythical creatures.

UNICORN HUNTING

The practice of an established couple seeking a single bisexual woman to join them, often with the expectation she'll be exclusive to them or "complete" their relationship. It's sometimes however criticized for treating the third person as an accessory rather than an equal with her own needs.

UPSIDE DOWN PINEAPPLE

The upside-down pineapple is a not-so-secret symbol used as a way for swingers to identify each other. Pineapples are known as a symbol of warm welcomes, celebration, and hospitality which swingers have adopted to let other like-minded people know that they are welcome and want to connect.
