The future of sex tourism lies in robot prostitutes, two Victoria University researchers have theorised.

Management professor Ian Yeoman, a futurist with an interest in tourism, and sexologist Michelle Mars have looked to how red light districts might operate in the year 2050.

The futuristic scenario of sex tourism suggests android prostitutes will reign supreme, eliminating the risk of contracting sexually transmitted infections in an industry free from sex slavery.

Their paper:  Robots, Men And Sex Tourism, published in the journal Futures, imagines a sex club in Amsterdam named Yub-Yum.

Sexual tourists will pay about 10,000 Euro for an all-inclusive service from massages and lap dances to intercourse from the scantily-clad sexbots parading around.

In an increasingly youth and beauty-fixated society, Yub-yum would provide a range ''of sexual gods and goddesses of different ethnicities, body shapes, ages, languages and sexual features.''

Yub-yum would be staffed by androids and licensed by the council meaning it could be regulated and used to market the city as a sex tourism destination.

''Amsterdam's tourist industry is built on an image of sex and drugs. The council was worried that if the red light district were to close, it would have a detrimental effect on the city's brand and tourism industry.''

The androids would be made of bacteria resistant fibre and would be flushed for human fluids, therefore guaranteeing no STIs are transferred between consumers.

Clients could feel guilt free as they actually have not had sex with a real person and would not have to lie to their partner.

''Robot sex is safer sex, free from the constraints, precautions and uncertainties of the real deal.''
