Full answer: -
A lot of ethicists and psychologists think that yes, they should learn to say no. Here is an interesting article about it:

Should We Program Sex Robots to Give Consent?

I agree with Kate Darling, Ph.D., a research specialist and robot-human interaction expert at MIT Media Lab, told Inverse in a discussion about Westworld, when she says she isn’t concerned about the robots, but with human behavior.

However, when I’ve expressed these feelings on Quora, about this controversy I was downvoted and my answer collapsed because people got offended that I made the claim that an object (the robot) could be ‘raped,’ even after I clarified exactly what I meant by that- that no you cannot rape an object, but just as an object cannot consent, you may be enacting ‘rape’ or torture fantasies, etc., on the robot. I think I was downvoted because my point of view wasn’t exactly what they wanted to hear, was too blunt, and the people who downvote opinions that may look more negatively at the sex robot industry typically aren’t feminists in the slight.

It seems a lot of people want the right to use sex robots and also that a lot of people haven’t really thought about it too deeply. Some people say that the robots will relieve women from sex work or protect people from sexual assault, I think these are very bold claims. Some people compare the sex robots to vibrators or other masturbation tools, but this is simply not accurate because sex robots are designed to be much more. They are marketed as companions that do not cry, nag, etc. People that own them often may dress them, tie them up, have marriage ceremonies, etc., a lot more activities than they would if it was a simple masturbation tool.
