LetUsBeCurious — trading as Luxuria Events — organises high-end erotic parties for open-minded couples at what it calls luxurious, sizzling locations throughout the Netherlands. The format is a dance event rather than a club night: a maximum of five hundred guests, an erotic atmosphere, the best beats, bites and drinks, and a building chosen to carry the theme. Past editions have taken over Kasteel Dussen and a secret villa in the south of the country.

Access is closed in a way few Dutch organisers match. The events are invitation-only: you first become a member through the website, and only members are given access and offered tickets, which are non-transferable. Membership runs at a modest annual fee and includes a discount on ticket prices. Single ladies can apply through the same form; there is no route for single men.

The dress code is black tie in spirit and precise in practice — for a recent edition, a dark two-piece suit with a matching shirt for men, white lingerie with a touch of gold for women, heels and accessories such as gloves, pearls or a tiara — with dresses, catsuits, jeans, flat shoes and trainers all refused. The organisers ask that it be respected by every guest, and the door is where that is settled.

How far things go depends on the room: the organisers state that sexual acts are permitted depending on the location and the event, that each edition has an intieme ruimte — a playroom couples enter together — and that you will not be confronted with sex in the public areas. Phones and other transmitting devices are banned outright, and photography is left to the official photographers. A ticket typically covers free parking near the venue, a staffed cloakroom or personal locker, a welcome bubble, free bites, the playroom, entertainment, a couple's photo shoot and a parting gift, with drinks bought separately using tokens.
