if you have submissive tendencies they will present in other areas than the bedroom. It isn't just a sexual thing. You could have some sub tendencies, you do say you've never had a "deep desire to be dominated by my partner" this could mean you are slightly submissive or it could just mean that you like the fantasy role. A true sub performs acts of submission in and out of the bedroom. Oh and just to add clarity to that, Submissive doesn't equal Slave.
