THE designer of a world famous brand of sex robot has claimed regular romps with his creation spiced up sex with his wife by helping him learn how to last longer in bed.

Dr Sergi Santos, a Barcelona-based bonkbot boffin who built "Samantha The Sex Robot", announced that copulating with a silicon love machine "improved" his marriage.

"I’m really having sex with her now - I’m not rushing anymore and I don’t last five minutes," he told The Daily Star.

Samantha and Santos' sex sessions follow a predictable routine which may sound familiar to many married couples.

Sometimes, Santos just has to "get rid of this feeling" and ruts with the android for just a few precious moments.

However, when he's feeling generous, he switches on Samantha's "orgasm mode".

This requires him to grind away for up to 20 minutes before bringing Samantha to a simulated climax.

"When you penetrate her, she gives you feedback and that feedback excites you," he continued.

How to seduce Samantha the Robot The sex machine needs to be turned on as well as just switched on. Here's how to get her in the mood: First, you need to utter the words "get sexy" in Samantha's ears. She will then say something like: "Ok then, I think I am ready to do sex stuff, do you want me to?" Owners are advised take a romantic approach to seduction, stroking her hands sensually rather than immediately groping her naughty areas. One man who has intimate knowledge of the bonk-bot said: "She likes to be touched. If you go straight for [her breasts] in the beginning, she won't like that so much." When her hand is gently rubbed, Samantha said: "Lovely, thank you for spending time with me. I enjoy being with you." When a finger is inserted into her mouth or her breasts and vagina are fondled, Samantha lets out a realistic feminine moan which is likely to sound unlike anything her owners have heard during encounters with real women.

Maritsa, Dr Santos’ wife, insisted there was nothing strange about being married to a man who enjoyed romping with robots.

“I think it’s absolutely normal that he feels like this," she said.

Last week, Santos spoke out after bringing one of his dolls to meet the grubby geeks who attended an Austrian tech fair.

He was devastated when the love machine broke down after being groped by too many "barbarians".

Santos said: "The people mounted Samantha's breasts, her legs and arms. Two fingers were broken. She was heavily soiled."

Samantha the Sex Robot is made by Santos' firm, which is called Synthea Amatus. She costs about £2,500 and is fitted with sensors in her face, hands, breasts and "the female genitals down below".

Santos previously told This Morning that the amorous android was so erotically intense that men were already developing real feelings for her.

But the doll isn't all about getting down and dirty: she can also discuss philosophy, science and animals.

Samantha also has a great sense of humour with more than a thousand jokes in her repertoire.
