Gangbang Parties Are Booming — 1,529 Events and 95,585 Guests in Germany in One Year. Who Goes, and How They Get Vetted

Search the word "gangbang" and almost every result is a video. Yet in December 2025, a German public broadcaster put the word in a news headline. The story was not about videos. It was about the number of real gatherings.

Germany: 1,529 in a year

JOYclub, Germany's largest sex-positive community, publishes an annual count of events listed on its platform. From October 2024 to September 2025, 1,529 events across Germany were classified as gangbangs, with 95,585 participants. Events rose 19% on the previous year, participants 24.4%. Bavaria alone had 421 — more than one a day — averaging 84.3 participants each. Growth was steepest in Hesse (+58.1%), then Bavaria (+45.2%) and Baden-Württemberg (+35.1%). (JOYclub press release, 17 Nov 2025)

Hessian public broadcaster hessenschau took those figures to Mike Laufenberg, a sexuality researcher at Fulda University of Applied Sciences. He cautioned that independent research would be needed to call it a trend, and raised the questions of commercialization and power imbalance. In Hesse, 264 of 2,190 adult events — 12% — were gangbangs, the highest share in the country. (hessenschau, 13 Dec 2025)

The platform's annual report shows the wider picture: more than 30,000 erotic events and more than 2 million participants in a year, one in three of them first-timers. Two out of three female first-timers came back. (JOYclub Event Report 2024, 26 Nov 2024)

Italy: a 25-year re-survey, three times higher

Italy's social research institute Censis repeated in 2026 a sexual-habits study it last ran in 2000. In a sample of 1,000 people aged 18–60, group sex and threesome experience rose from 0.7% to 6.8% among women and from 3.2% to 20.1% among men. In the same survey, 80.4% were still in a stable relationship with one partner. (Il Fatto Quotidiano, 24 Mar 2026) Most people who tried group sex did so inside a relationship, not instead of one.

France's national sexuality survey by Inserm found that 23.9% of women and 32.3% of men had more than one partner in the past 12 months in 2023, up steadily from 9.6% and 22.9% in 1992. (Inserm, 13 Nov 2024)

The fantasy is already being acted on

In 2025 JOYclub asked 4,299 members whether they had acted on a group-sex fantasy. 64.9% of women and 63% of men said yes. Only 9.8% reported strong jealousy. 63.6% said agreeing rules in advance was important, and 40.9% had agreed a safeword. (JOYclub, 1 Apr 2025) Nine in ten got through it without a jealousy problem — a figure that should be read alongside how many set rules first.

Argentina: a community counts itself

Argentina's swinger association ASLA ran the country's first community census in 2024. Of 1,300 respondents, 45% lived in the Buenos Aires suburbs; the largest age group was 41–50 (39%). Couples were 66%, single men 27%, single women 6%. (Infobae, 24 Sep 2024) The association estimates about 1.3 million Argentines practise the lifestyle — its own estimate, not an independently verified figure. The rule at its biggest annual party fits in one line: "There is no second question. No insisting." (Infobae, 25 Apr 2025)

The other side of the boom: vetting

The bigger the numbers, the more the door matters. Swingathon, the UK's largest swinger festival, doubled to more than 1,000 attendees in 2024. Organizer Matt Cole describes the entry condition: prove a history on an established community platform, or be vouched for by an existing member. "Every person in this field is vetted, we don't just let anyone in." Gender balance is enforced, filming is banned, STI testing is encouraged. 2025 tickets were £210 single and £250 per couple; 30% were first-timers and 50% returning. (LADbible, 18 Jul 2025)

The counter-example came the same year. São Paulo's best-known swinger club raised its Saturday couples' entry from R$215 in 2023 to R$285 in 2025, and Folha de S.Paulo reported that participants were shifting from paid clubs to home gatherings and apps. One community app in Brazil's southeast added 836,000 new sign-ups in 2024. (Folha de S.Paulo report, 10 Aug 2025) The club replied that facilities you cannot recreate at home are its edge. (Spicy Club response, 18 Aug 2025) The core of the argument is simple: people spend money and time not on rooms but on knowing who will be in the room.

How ZAVOS reads these numbers

ZAVOS is not surprised by Germany's 1,529. The Seoul community has run gatherings of this kind since 1999. What is striking is not the number but that the same mechanisms appear everywhere the numbers grow: screening, vouching, STI testing, no cameras, rules agreed beforehand.

ZAVOS member meetups have those mechanisms as defaults. Membership passes host screening; women become full members after an in-person interview; STI test results are checked at the door before a meetup and destroyed on the spot. No money changes hands. Germany's boom happened on commercial platforms. ZAVOS takes the same demand into city-based member communities.

Frequently asked questions

What is the difference between a gangbang and an orgy? A gangbang centres on one person with several participants; an orgy is several people mixing with each other. The German count covers only events classified as gangbangs.

Are the German figures reliable? They are one commercial platform's own count. The researcher interviewed by hessenschau made the same point: the direction is clear, but the absolute numbers are that platform's.

How many are first-timers? One in three in the German count; 30% at the UK's Swingathon.

Is there an entry fee at ZAVOS meetups? No. Venue and food costs are split equally among attendees, and hosts are unpaid.
