Human sex workers are fighting back against sex robots, claiming they are dehumanizing and could turn users into predators.

Three women who work at Sheri's Ranch in Nevada toldThe Sun they were firmly against the new technology, which has created dolls that look like humans, used for sex acts.

They say the dolls are dehumanizing, encourage violence against women and promote a lack of empathy in sexual scenarios.

Red Diamonds told the paper because the robot was not a person, the issue of consent would never come up, which could blur the lines for some clients.

'Real sex, especially real sex with a sex worker, is a consensual situation where all parties respect and appreciate their lovers,' she explained.

'Sex doll brothels encourage disrespect toward women and promote a lack of empathy in sexual interactions.'

Diamonds says this change can lead to dangerous situations for future partners of the robot user.

Her colleague, Roxanne Price, thinks similarly, telling the paper she believes the legality and availability of the robots promote violence against women by normalizing abusive behavior.

'The idea that women should be like dolls – unresponsive and lethargic during sex – is downright dangerous,' she said.

'I feel sex doll brothels support the idea that sex workers are mere objects, devoid of agency, to be used and abused by their patrons.'

Sex robots are slowly beginning to appear in brothels around the world as an option for clients.

Russia opened its first just weeks out from the World Cup in Moscow, and in Austria, brothel customers already prefer robots over sexual intercourse with a human.

The dolls are slowly beginning to pop up all over the world, but have not received a warm welcome in the USA

The robots have even made an appearance in Australia, with a selection of them flying down under for Sexpo earlier this year .

But the bots have not received a warm welcome in the USA, and Sheri's Ranch employee Allissa says the complaints of sex workers are not made with only their interests in mind.

'It's dehumanising,' she said.

'When a client sees a human sex worker, he has a real two-way experience with a woman that gives him feedback and enhances his ability to be intimate with other women in his current or future life.'

Allissa said while this experience would improve the client's life and future prospects with potential partners, it was not possible to replicate with a robot.
