For my BDSM interests - the D/S is my main purpose. S&M is quite fun (I tend to be on the mild to moderate side of sadism), and bondage can be enjoyable (I have no real skill in it), but the dominance and submission aspects are the true appeal for me. While my kinks and fetishes tend towards the average (at least for a place like this), my extremity is in the level of control I'm seeking, the thoroughness of submission I'd hope to receive. 

With that in mind, if your primary reason for looking to submit isn't the act of submission itself, it's unlikely that we're a match. Not to say that more casual play is completely impossible for someone particularly exceptional in some way or another, but my wife and I are both more shallow than we are attractive which lends to a mismatch in expectations for purely physical exploits. 

So then, what do I offer? Stability, control and use. Stability: You'd belong to someone that thinks before he acts, and typically acts with purpose. You'd belong to someone that isn't looking for temporary or short term. If we connected, you could have a forever home. Control: My goal is total power exchange. You giving up control over every aspect of your life and body. Major and even many minor decisions won't be something you have to worry about. That said, I don't want a robot that needs fully programmed to do each task, I'd expect you to be able to be given a task and to complete it without every step being dictated. 

This brings me to use. I am offering to use you. That may sound like such a non-offer, a non-contribution. However, I've found, somehow, that even in certain circles people really won't make full use of another. Sure, any guy will use your body to get his rocks off... but will he do absolutely everything he wants? And of course, outside of that, will they make sure to use you in every way that is pleasing, beneficial or useful?

I accept that submission is a gift, and I don't want to waste it on half measures if it's being offered in full. If you're someone who gets their true satisfaction know that they've pleased and been useful, if getting that specific smile or that "good girl" is worth more to you than the best orgasm or the nicest gift, then you might be a match for the Dom whom hearing "yes Sir" typically brings as much pleasure as the act that follows it.

Some additional notes: I have no interest in anything online other than as a vehicle to get to know each other and develop a comfort level prior to meeting. Be prepared to verify yourself in some fashion fairly early on in conversations. Bonus points if you're nerdy, but that isn't necessary if you bring the level of submission that I'm seeking. Also, yes, the wife very much knows and supports the search, her level of interest will depend on you.
