I would like to be in a separate room of a swinger club, tied to a bed, spread-eagled for the whole night. Anybody can do anything with me.

People will abuse me sexually and punish me if I am not cooperative (However pain and punishment is just "background" - the important thing is being helplessly exposed to many unknown people). I can not quit, they won't let me go. The swinger club operator takes care that I won't be injured, but thats the only protection I have.
