I think it can be both submissive and empowering depending on you and your lovers mood. Sometimes when I'm going down on my boyfriend I feel well in control, the boy helpless to the act. There's also the sense of power when he's pursuing, in need of, sex from me. He's damn near a little boy lost, unable to function, until I pull his trigger and release his pent-up desires. As if I'm the only one in the world who can ease his pain. And then there are other times I feel the willing submissive especially if he's in one of his sexually aggressive moods and dominating me physically, being forceful in what he wants, which I absolutely adore.
There are also times when it's a bit of both like when he gets home from a hard day's work and is just out of the shower and relaxing/exhausted on the sofa. It's time like those that I totally embrace the traditional male/female sexual roles. I'm eager to please him and take his stress away, show him how much I love him and appreciate what he does for us, you know, remind him what comforts and spoils are waiting for him at home for all his efforts. The whole modern idea of feminism and equality is thrown to the wind and I don't think I ever feel more sexually content in my female skin than when I'm in those moments. As I'm in the act there's this sense of me being his sexual slave which is a huge turn-on and yet his masculinity and body are literally in my hands (and mouth). A, his body is mine and mine is his type of thing. Both parties are fully exploiting each other and there's not a complaint to be had. There's nothing more satisfying/comforting both physically and emotionally for me than to abandon myself and become his. A lot of times when I'm giving him a blowjob I feel that way.
Lay back and relax babe, I'm going to make you feel like a king. My king. Truly relationship bliss.
