When directed toward me, there are behaviors that, no matter how blatantly transparent, manipulate me; they speak to something inside me, gratify me, and invoke a clarity of thought and aggressive focus nothing else does. These are the methods by which a partner turns me on most.
The primary factor here is docility. What arouses me most is weakness. A woman's behavior ought to indicate some vulnerability to me: she should be unsure, needy, even a bit desperate. I'm turned on by clinginess. When interacting with a woman, I want her to seem off-balance. When she blushes and looks away, when she has a wound in her heart, I'm attracted; when she defers to me, looks to me for guidance in a situation, I'm attracted; when she's completely lost and doesn't know what to do, I'm attracted; when she's close to me, afraid of something and finding me strong, I'm attracted.
If you want to arouse the dominance in my behaviour, you need to show me the submission in yours. Make it clear that my opinion matters to you more than other people's. Make it clear you want to be in my presence. When you speak, don't speak of preferences or desires; speak of needs. You need me to bathe you and help you put on lotion. You need me to brush your hair. You need me to pick what you wear. Be shy and demure.
If, when you look at me, I feel you're looking up at me, you are small and lovely in my eyes.
If you stare at me and talk to me first when you walk into a room, I will notice that. If you're making bored small talk with other people but light up when I approach, I will notice that. If you step in closer to me and open yourself via body language, I will notice that.
Respect me. More than that -- worship me. Listen raptly to me. Stay near me. Look up at me. Smile and glance away. If I talk to you, look at no one but me. Show weakness. Defer to me. Adore me. Need me. Confide in me. Look to me for help and guidance. Be sad. Be afraid. Be helpless and lost. Make yourself small and tuck yourself against me.
If you want me to be dominant with you, you need to make your interest and inclination to submit to me clear. It does not need to be made explicit, once we begin this game I will be focused very intently on you, but you need to send out signal after signal, and trust that once you've sent out enough for me to judge you subservient I will move on you fiercely.
Things I look for: shy smiles, blushing, downcast eyes, lingering parted lips, facing me, self-touching, lingering proximity, eagerness to please, enthusiasm toward me specifically. There are more, but honestly, this specific example part is the weakest and least important. Body language, the way one speaks, these things vary person to person, and instead of any one individual piece, it's clusters that generate significance. The key is to behave in ways that show explicit or implicit giving of yourself to me.
This is especially important when we're deeply conversing or interacting more intimately. I want your devotion, loyalty, and submission more clear -- I want to know you're needy. I want you to cling to me and look to me for approval.

Public me: For the outside world I'm a Professor, reserved, well liked and have my life together. I'm 30 years old, 6'3'', fit but not jacked, attended top schools, well traveled, speak 4 languages, and have a range of eclectic interests. I will be in Boston for 6 months.

Private me: In the bedroom, I enjoy control and I take over. I'm sadistic, rough, somewhat manipulative, demanding and unpredictable. Beyond the physical, I crave having someone to mold and make better. I want someone to use and control yes, but I also want someone whom I can help improve; to help her achieve her goals, set timelines, establish objectives and administer punishments if not met.

Next Steps: Shoot me a chat with a brief description of yourself, your favorite class in college and tell me why my post appealed to you. Go!
