Are sex robots a threat to real prostitutes? A pair of New Zealand researchers say yes, finding that robot prostitutes will revolutionize the sex tourism business by 2050.

Robot sex is safer sex, free from the constraints, precautions and uncertainties of the real deal, wrote Victoria University management professor Ian Yeoman and sexologist Michelle Mars in their paper, titled Robots, Men And Sex Tourism.

The paper is published in the journal Futures and was first reported by New Zealand's Dominion Post.

Robots, Men And Sex Tourism describes an imaginary sex club in Amsterdam called Yub-Yum, where sex tourists pay 10,000 euros ($13,191) for massage, lap dances and straight sex from sex robots strutting around the club.

The club would resemble others in Amsterdam's Red Light District, the researchers wrote, saying Yub-Yum would contain sexual gods and goddesses of different ethnicities, body shapes, ages, languages and sexual features.

Sexually transmitted diseases and infections would be non-existent, Yeoman and Mars said, because the sex robots would be made of bacteria-resistant fiber that would be flushed of human fluids after the sex acts.

While the New Zealand study is bad news for prostitutes, Dennis Hof, owner of the Moonlite Bunny Ranch, a legalized brothel near Las Vegas, scoffed at the findings, saying nothing beats the real thing.

Those Australian researchers ought to come to the Bunny Ranch to see what real American sex is like -- there's no way to duplicate it, Hof told CBS Las Vegas. At the Bunny Ranch, we say 'it's not just the sex, it's an adventure' -- and often times it's more about the adventure than it is the sex.
