Don't get me wrong a great BJ is a great  BJ, whether I am sitting, standing, or laying down; however, there is just something extra sexy about getting that great oral standing up with a sexy lady on her knees in front of me.  

Great question!! I have three favorite positions when it comes to giving- firstly, as you mentioned, on my knees while my lover is standing or sitting- it gives a great visual for both of us, I can pay lots of attention to the boys, there is lots of opportunity for eye contact, and I can usually DT if a gent's member is not curved upwards very much, or if he is not terribly long. I also love laying a gent on his back to just relax and enjoy while I kneel or lie down and slurp and suck my way into his heart. :P For maximum DT, especially if someone is bigger or curved upwards, 69 is the best position!  
In terms of receiving, I love being on my back, bent over something or in doggie position. If I'm feeling super trusting and intimate, lying down together and getting off while we kiss and I'm being stimulated manually is just the best feeling in the world.

lady friends kneeling on the bed or on the floor.  
Don't know why, maybe it's a subconscious dom thing.

DT for sure has to be  positioned

...There is just something so amazing and intimate about having a Woman's warm ass cheeks on my face while I pleasure her.  

I am a professional so I can always make it happen. If you have it, I will work it.

But I'll never ask her to get on her knees, or squat.
