Expressing breast milk!?

Just wondering if anybody else is planning on feeding exclusively pumped breast milk? I have an electric breast pump that has some pretty good reviews so don't think that will be a problem. I just feel to weird about breast feeding naturally, I knows it's natural and all but I've tried so hard to get my head around it and can't, but I still want to give my baby the milk to give her the best start in life and keep her as healthy as I can.
