Hmmm...I'm another one who's Christian and feminist, although I recognise that there are different interpretations and gradations of feminism, and there are feminists who wouldn't call me a 'real' feminist....just as there are inrerpretations and gradations of Christianity and there are undoudtedly those who wouldn't call me a 'real' Christian! 
Yes, the church is veeeeery androcentric, even the nice liberal parts of it. What it comes down to, to me is this:
I believe it's true - I believe that Jesus was God incarnate, the saviour of the world. If I didn't believe that, there'd be no point being a Christian.
And yes, of course it's a mystery - if it weren't, it wouldn't be worth believing in. If I could fully explicate God, I'd not be explicating God but an idol of my own making.
And...I believe in 'progressive revelation' (i.e. change), the 'long, winding road' towards a better understanding of God. I believe that the ordinaton of women was a step along that road, and that women bishops will be the next step.
And also - if all the women / feminists left the church, it really would be androcentric! And I love it too much to be part of its demise.
And, while I'm on it, gendered personal pronouns really get my goat! I an reading a lot of 20th century theology at the moment and am getting sick to the back teeth of reading about 'the relation between God and man'...grrrr. The good news (well, it'll make me feel better, anyway) is that I am going to sit an exam this summer in which I can write as a Christian feminist. So I've got a bit of a right to reply!
As an aside (sorry if I'm rambling), I'm thinking about going into academic biblical scholarship as well as being ordained. It's saddening that the vast majority of biblical scholars are male. So the way in which theology is being done that shapes the mind of the church and has an impact on what is peached from the pulpit, is all very androcentric. And again, I care too much about the church to let that be the status quo. So I'm applying to a biblical doctorate after my degree....yikes! It'll be hard work but a labour of love, not only of the bible itself but also of the people who might benefit from it, esp. women.
