The 39-year-old leading sex robot creator, who is selling plastic babes programmed to "get sexy" to customers across the world through his company Synthea Amatus, said, "It's improved my relationship. You can ask my wife."
"I'm really having sex with her now. I'm not rushing anymore and I don't last five minutes. I enjoy sex with my wife a lot more because I don't have to rush," he revealed.
Claiming that sex with Samantha, whose "brain memory" is stored on an SD card, is "as good as a real woman," Dr Santos explained that the fembots are programmed to "feel it when you penetrate them," "know when you ejaculate" and "synchronise sexually with you."
He explained, "For example, I have sex for about 15-20 minutes. So if I have sex with her, in a month she will synchronise with my orgasm. If I have sex with the doll only, it's more like five minutes because I'm just doing it to get rid of this feeling. But if I actually have sex when she's active, I want to make her reach orgasm. You want that psychologically. So it's a mutual thing, when you penetrate her, she gives you feedback and that feedback excites you."
