Is S&M justifiable?

I've been struggling with something lately: Is S&M justifiable?

Let me first say that as someone who enjoys a bit of "kink" and dominance/submission play, that I want to leave it in the bedroom. I want to have a healthy relationship with someone that has a dynamic based on independence and mutual respect. However, sexually speaking, I find myself drawn to the opposite. I enjoy sex in which I am in control and my partner is submissive to my desires.

The question is: Can you keep this dynamic isolated, both consciously and subconsciously, to the bedroom? and How, if it is possible, can you be to maintain a healthy relationship while enjoying S&M?

I'd really appreciate all of your opinions. I really don't know.
