A new Berlin venue that markets itself as Europe’s first immersive “cyber brothel” is drawing criticism and raising questions about how advancing sexual technologies might reshape social norms around consent and violence.
The establishment, known as Cybrothel, combines silicone sex dolls, virtual-reality software and, increasingly, interactive artificial intelligence in private rooms marketed as discreet spaces for mixed-reality sexual experiences. Visitors are shown a range of doll characters and can book sessions that include equipment such as lubricants, condoms, latex gloves and motion-tracking hip controllers that sync a user’s movements with a virtual avatar.
Journalist Laura Bates, in an excerpt from her book The New Age of Sexism, described entering a dimly lit room at Cybrothel and encountering a doll named Kokeshi laid out on a king-size bed. Bates wrote that the room also contained a chair with stirrups resembling a medical examination chair and that the dolls and the venue’s online imagery at times presented graphic or fetishized scenarios, including a doll shown covered in blood and a website image that once depicted a decapitated doll.
Cybrothel presents its offering as an experiment that "blurs the lines between reality and virtuality" and a way to normalize the use of AI, robotics and immersive experiences in people’s sexual lives. The venue collaborated with digital studio Polybay on a game, Cherry VX, that uses a headset and wearable sensors so players see and feel the actions of a virtual partner while physically interacting with a doll. Cybrothel co-founder Matthias Smetana, in correspondence cited by Bates, said the technologies developed at the venue will become more common and could help people struggling with loneliness, social isolation, disability or limited access to compatible partners.
Critics say that framing raises ethical and social concerns. Sex workers, activists and some researchers warn the venue’s format can manufacture the illusion of consent because dolls cannot refuse or set boundaries. Madelaine Thomas, a U.K.-based sex worker who performs as Countess Diamond, told reporters that dolls that never say no can train consumers to expect sexual encounters where their desires are always met, potentially undermining respect for boundaries with real people.
Researchers have also raised alarms about correlations between attitudes toward sexual violence and hypothetical behavior in anonymous conditions. Bates cites a study published in the journal Science and Gender that found a portion of surveyed men indicated they would have sexual intercourse with a woman against her will if they believed they would never be found out and there would be no consequences. Such findings are used by some critics to argue that venues offering staged or simulated violence risk normalizing aggressive behavior.
Owners and operators of doll brothels elsewhere in Germany and Europe have reported requests for role-play that some describe as violent. One proprietor cited in reporting said some clients prefer to enact rape fantasies, and other venues have offered themed rooms that simulated settings such as schoolrooms or medical-examination environments. Advocates for consensual BDSM stress that consent and negotiated boundaries are fundamental to those practices, and they express concern about presenting nonconsensual or violent scenarios with nonhuman partners.
At Cybrothel, Bates described a largely contactless customer journey: patrons are buzzed into a second-floor apartment, escorted to a private room where a doll awaits, and depart without encountering staff. The venue reported a clientele that is overwhelmingly male; Cybrothel materials and reporting cite a roughly 98 percent male, 2 percent female customer split. Bates and others also pointed to accessibility gaps at the premises, noting steep stairways and a lack of adaptations for patrons with mobility impairments, which she said undermined the argument that the venue serves people with disabilities.
Cybrothel has continued to expand the technological capabilities of its dolls. Smetana told Bates the firm aims to create dolls that can move, react and deliver lifelike haptic sensations through electromechanical actuation and sensors. He said a new AI program will allow clients to interact verbally with dolls, enabling two-way exchanges that the venue markets as increasing realism.
Those technological ambitions sharpen the debate about social effects. Supporters say robotic sex technology could offer solace or companionship to people who are otherwise isolated, including older adults and people with disabilities, and could reduce demand for riskier or exploitative human services. Opponents argue the commercialization of sexual interactions with programmable, compliant bodies may entrench harmful gendered power dynamics and erode norms around mutual consent and empathy.
Sex workers’ groups warn that the widespread normalization of sex with unresisting, controllable bodies may shape client expectations in ways that increase risks for human partners. Bates and other critics contend that the earliest harms are likely to be borne by already vulnerable groups, including street-based and indoor sex workers, before broader societal effects become apparent.
European regulators and legal frameworks governing brothels, sexual services and consumer safety vary by country, and public debate about robotic sexual technologies remains in early stages. Some operators have voluntarily removed graphic imagery from promotional materials after public outcry, while others continue to offer themed experiences that blur role-play and fetish content.
The Cybrothel case illuminates a broader cultural crossroads as developers integrate robotics, AI and immersive media into sexual entertainment. Advocates for safeguarding and reform say that discussion of these services must include attention to consent education, the safety of human sex workers, accessibility, and potential downstream effects on attitudes toward violence and intimate-partner abuse. Researchers and advocacy groups call for more data on how extended interactions with lifelike sexual robots affect users’ real-world behaviour and beliefs.
For now, the industry’s trajectory appears to be toward greater realism and interactivity. Smetana and other developers describe that path as innovation; critics describe it as a social experiment with potentially dangerous side effects for women and vulnerable people. As these technologies move from niche venues into wider commercial availability, regulators, researchers and service providers face the task of weighing and responding to both promised benefits and the concerns raised by advocates and frontline workers.
