The first owner of one of the world's most advanced sex robots says he is considering making one his full-time GIRLFRIEND.

The 60-year-old Californian man, who goes by the alias Brick Dollbanger and claims to have spent £150k on sex dolls over the years, described owning £11.7k 'Harmony' as fantastic - but says a forthcoming setting allowing her to physically respond to foreplay will make the experience even better.

The father-of-two described the Harmony doll from California-based company Realbotix as a "work of art" during an interview with the Daily Star..

The firm claims the new setting, called X Mode, will allow Harmony to "fulfil your wildest sexual desires".

The doll is already able to remember its owner's favourite food, film and music, and Brick said X Mode would also allow it to responds verbally to different actions.

“It’s a sensor that can tell when she’s being jostled around," he said.

“When she’s switched in the X mode the sensor will go live, she’s going to know what you’re doing."

Brick said companionship was the driving factor behind his decision to buy a sex doll and claimed other lonely punters were also seeking the same thing.

Brick, who has spent around £150,000 on sex dolls in the past decade, once said he has more fun with them than his 1980s Corvette.

The rise in availability of artificially intelligent sex robots has caused concern among psychological experts, who believe it may fuel a rise in sex addiction.

Psychological therapist Dr Thaddeus Birchard told Daily Star Online that life-like robots featuring AI could be another outlet for sex addicts to express their compulsion.

Dr Birchard, who serves as the clinical director of the Marylebone Centre for Psychological Therapies, said they served the same purpose as alcohol for people with drinking problems.

“It would just be another way of expressing sexual activity or addiction,” he explained.

On the flips side, creators of the bots claim they could prove a boon for struggling marriages and lonely or disabled men.

Realbotix's founder and CEO Matt McMullen has cited replacing sex work with his firm's bots as an ambition.

Artificial intelligence expert Dr David Levy, author of Love and Sex with Robots, has also said androids will "significantly reduce the incidents of STIs".
