Transgender dolls with male and female genitalia are being shipped across the world as the global market booms.

THE soaring demand for transgender sex robots is being driven by adventurous couples keen to experiment in the bedroom, a sex expert has told Sun Online.

“Specifically, heterosexual men will use transgender dolls because a very large proportion of them are interested in transgender porn.

She said: “It is not surprising to see the rise in popularity of transgender dolls.

But Sari Cooper, a sex therapist and sex coach, told Sun Online they will instead allow straight men to copy what they see in their favourite porn and let kinky couples have fun in the bedroom.

DS Dolls, a firm based in Dalian, north-west China, is also offering its customers “penis and vagina attachments” for the trans robots and reckons the move will appeal to the female market.

6 Some critics claim sex robots are unethical and damaging to society “I think, given that it [transgender porn] is of particular interest to heterosexual men rather than women, transgender dolls will work for more adventurous couples. “If women are interested in strap-ons for instance, they may want to use those with the dolls. “There are people who are interested in transgender porn who may want to re-enact what they see in that porn with these dolls. They may want to go swinging together, or go and visit a dungeon for instance. “I am in wonderment about the ways people are curious for novelty. It reflects the porn we see.”

DS Dolls believes transgender sex robots will help change the stereotype about the seedy industry. But Ms Cooper, who is the director of New York-based therapy firm Center for Love and Sex, added: “Men will be the main consumers of transgender sex dolls. “I think they [sex robots] are wonderful in providing opportunities to transform sex lives, and give couples opportunities to discover. I think they enhance relationships if they open up novelty. “Younger people are talking to me about monogamy with views that are open and new. “They are adventurous but sometimes have trouble articulating with their partner. “Some dolls encourage violence against women. As long as these new ones don’t use this rape setting, they’ll be fine additions.”

DS Dolls produces more than 400 sex robots every month. It charges more than £3,000 for its premium dolls. A spokesman for Cloud Climax, DS Doll’s flagship reseller in Europe, told Daily Star Online: “We have transgender dolls – a lot of our customers are female and a lot are couples as well. “We want to bring sex doll products into the forefront of the market and get around the prudishness and the thinking that they are just for men.” But the dolls were slammed by Kathleen Richardson, a professor of Ethics and Culture of Robots at De Montfort University Leicester who runs the Campaign Against Sex Robots.
