As a pure fantasy - yes.
For me, the feeling being exposed to some kind of cold, unfeeling force, is a favorite fantasy. Machines, Aliens - things I can't control or negotiate with. People who talk about me and the procedures they want to admister, like if I am not in the room and such.
There is even a story in my mind, I have to write at some point, about being abducted by some clandestine research institute and brought to a hidden facility for multiple sexual experiments...
Another dream of mine would be abducted (ans subsequently forced to have sex / being masturbated) by aliens for unknown reasons.
Or being exposed to an array of machines controlled by an A.I....
There are two limits - even in fantasy for this:
First, it might be an stoic, unnegotiable unfeeling power, controlling me, but it has to be ultimately benign (like the Institute, that wants to discover the ultimate orgasm, or researching new ways of stimulating people, or aliens who need loads and loads of human semen for unknown reasons..)
Second it has to be finite in some form i.e. the Institute / the aliens drop me off after conducting their experiments, probably with erased memory or something.
In reality: There are some dominatrixes or specialised adbuction companys I've heard of. But I think they go more for the 'abduction' part, than the 'perverted experiments with lots of orgasms' part. And it's really expensive. It's dangerous on some levels - you just don't know to what you signed up and even things, like getting spotted while being abducted, might lead to police investiagions and stuff.
And this counts if you aren't in a relationship, what I am. My wife surely wouldn't be that fond of the whole idea...
So I think this one should stay a fantasy and probably some stories of mine.
