The rules

The rules of Sulfur are relatively simple, but they are strict and non-negotiable. They are therefore intended to be strictly adhered to. They form the very foundation of the club, making it what it is: a unique environment that cannot be found anywhere else (to the best of our knowledge, at least; which is, in part, the reason for its existence).

Internal Rules of the Sulfur Club

Last update : 20 March 2026

The Sulfur Club is a private society where every evening is an exceptional experience, blending elegance, mystery and an exploration of boundless possibilities. To ensure that these moments remain unique and harmonious for all members, everyone is asked to observe the following rules when attending our events. These rules, based on mutual respect and discretion, are essential to preserving the essence of our society.

1. Respect for members’ anonymity

All members are required to maintain the absolute anonymity of their peers, in accordance with the non-disclosure agreement (NDA) signed upon joining. It is strictly forbidden to reveal or attempt to discover the true identity of another member, either during or after the event. Please use only the assigned pseudonyms for all interactions.

2. Adherence to the dress code

The dress code, as detailed in your invitation and in the privacy policy, is mandatory. Our events require elegant and refined attire (unless the theme of the evening calls for a different style, in which case this will be explicitly stated in advance), in keeping with the sophisticated atmosphere of the Sulfur Club. Any breach of dress code will result in refusal of entry to the event, without exception.

3. Punctuality and adherence to entry procedures

Arrival on time : Doors open at the time stated on your invitation and close 30 minutes later, after which the Sulfur ceases to exist for anyone who has not been granted access for whatever reason. Late arrivals will therefore not be tolerated, in order to ensure the smooth running of the evening for everyone.
One-time password : A password will be sent to members via text message or instant messaging just one hour before the event. This password, which changes every evening, must be provided at the entrance (either verbally or via your phone). Do not share it under any circumstances.

4. Adherence to the set themes

Each evening may include rituals, activities or specific guidelines (e.g. designated areas, specific interactions). These guidelines, which will be communicated at the entrance or during the event, must be strictly followed to ensure a smooth and immersive experience for everyone.

Generally speaking, a theme is assigned to each evening and announced in advance. No one is obliged to like it. Club members are therefore asked to consider whether their choice of attire for the evening is appropriate for the proposed theme. If they agree to the theme, it must be strictly adhered to by everyone present, failing which they may be excluded from the evening.

All members present are expected to fully engage with the evening’s atmosphere, during which no one should wait for others to take the initiative before following suit. Everyone, in keeping with their own personality, is strongly encouraged to overcome their inhibitions and demonstrate the utmost boldness, whilst always showing unconditional respect for others. This is not about giving free rein to one’s baser instincts, but about unleashing one’s potential for sexual expression, with as few limits as possible, in order to set the evening alight in a way that only Sulfur knows how!

4.1 The "no" policy

"No" means NO, and we will make sure of it. It is neither a disguised "yes" nor even a "maybe". It is therefore the responsibility of those who invoke it and use it against anyone not to try to play a double game by attempting to convey something other than what the word itself expresses; this one, like all the others. At Sulfur, a cat is a cat. Nothing else. No judgement either, just enjoyment.

That said, nobody comes to a Sulfur event just to sit there and say no. Coming along just to say "no" is a waste of everyone’s time. Traditional swingers’ clubs are sure to satisfy sex tourists, voyeurs and passive onlookers. Anyone may find themselves in a situation where they feel compelled to refuse, and such a refusal must be respected unconditionally. However, any member who makes a habit of refusing requests on a more or less systematic basis will be asked to leave the club. Our distinguished members come to our events knowing exactly what they want, and we make sure they find it.

5. Code of Conduct

If there is one thing of paramount importance at the Sulfur Club, it is going home having had a (very) good evening. To this end, under no circumstances will any arguments, domestic disputes, or obvious and unpleasant loss of control due to alcohol or drugs – or any other reason, however legitimate it may seem at first glance – be tolerated.

As such, our club is characterised by joy, pleasure and the alchemical transformation of your wild nights out into luxurious, sensual evenings.

Respect for other members : Any form of inappropriate, disrespectful or aggressive behaviour (whether verbal or physical) is strictly prohibited. This includes, but is not limited to, discriminatory remarks, unwanted advances made without allowing the person concerned to respond at their own pace and in a manner that suits them, or any behaviour that disrupts the harmony of the evening.
Respect for staff and the premises : Treat staff, any external service providers hired for the occasion, and the premises with the utmost courtesy. Any damage caused to the premises or equipment will be charged to the member responsible

6. Photography, film and audio recording

To protect everyone’s privacy, it is strictly forbidden to take photographs, videos or audio recordings during the events. Mobile phones, tablets and other electronic devices must be used solely to show the password at the entrance, if required, and must then be put away. Specific areas are provided for emergency calls, if necessary.

7. Responsible consumption

Drinks : Alcoholic and non-alcoholic drinks will be served as part of the sensory experience. Moderate consumption is required to ensure your safety and that of other participants. Any excessive behaviour related to alcohol will result in immediate exclusion from the event.
Illicit substances : The use or possession of illegal substances on the premises of the venue hosting the event is strictly prohibited and will result in permanent exclusion from the Club, as well as legal action if necessary.

Once admission has been granted, drinks are free for members. Please note that "at your discretion" does not mean "all you can drink". The club reserves the right to refuse to serve alcohol at its own discretion.

8. Post-event discretion

In accordance with the NDA (non-disclosure agreement), no information about the event (venues, attendees, activities) must be shared outside the circle of members present. This includes private conversations, social media, or any other form of communication. The mystery of the Sulfur Club is an asset that its members help to protect jealously.

9. Management of personal belongings

Prohibited items : Weapons, dangerous items or any unauthorised materials are strictly prohibited. A discreet search may be carried out at the entrance.
Cloakroom : A secure cloakroom will be available. The Club accepts no liability for the loss or theft of any items not left in the cloakroom.

10. Non-disclosure clause

Membership of the Sulfur Club requires the signing of a non-disclosure agreement (NDA) regarding the identity of its members, as well as the known dates and venues of scheduled events. Please note that, as you will have realised if you have already browsed a few pages of the website, we place the utmost importance on the anonymity of our members. We are prepared to go to any lengths to achieve this, within the bounds of the law, of course. The signature we require from our members, affixed to their firm commitment to maintain the strictest confidentiality regarding the identity of other members, whoever they may be, as well as concerning the dates, venues, themes and instructions prior to scheduled events and those that have already taken place, is the cornerstone of the Sulfur Club. As such, we require a legally binding electronic signature from each member, which can therefore serve as evidence against anyone breaching this commitment should this secrecy be compromised. This measure will ensure that everyone, without exception, is afforded the utmost respect for their anonymity.

The text of this clause is available to read online and download. If you wish to sign up, you will need to sign it via the eSignatures website.

11. Consequences of a breach of the rules

Any breach of these rules will result in immediate sanctions, depending on the seriousness of the offence:

Warning : For minor offences (e.g. being slightly late, unauthorised use of a mobile phone).
Exclusion from the event : For minor offences (e.g. inappropriate behaviour, failure to comply with the dress code).
Cancellation of membership : For serious offences (e.g. breach of anonymity, use of illicit substances), with no refund of membership fees and potential legal action where applicable.

By attending a Sulfur Club event, you agree to abide by these rules, which ensure a harmonious and memorable experience for all members. Our circle is built on trust, discretion and elegance – values that we invite you to embody at all times. Immerse yourself in the mystery, savour the moment, and let yourself be swept away by the extraordinary.
