Notable Examples: Barbarella (1968), Weird Science (1985), Austin Powers: The Spy Who Shagged Me (1999)

The movies love robots, but seldom do they show up in the bedroom. And when they do, it's often not a good thing. Just ask Barbarella. In Roger Vadim's 1968 classic, Barbarella is trapped in the Excessive Machine, a device designed to torture the subject to death with pleasure. But Barbarella is too tough for it and the machine breaks down giving her orgasms.

In the sequel to the first Austin Powers, the British spy comes to learn that his wife, who he's been having zesty sex with, is a Fembot. Then she tries to murder him.

But on the other hand, there's Kelly LeBrock's character in Weird Science, the creation of a computer. She only makes good things happen.
