Breastfeeding help!

My son is a week old today. He still will not breastfeed.

My nipples dont want to seem to get erect enough for him (if that's the right term), and when they do sometimes after pumping a little first, he will MAYBE suck on them for a few seconds and give up. And they go flat again.

He prefers how much easier a bottle is, but I do not want to pump exclusively for him. He gets very angry when I try after a few minutes. I am at a loss of what to do and I need some serious help! I feel like if he doesn't do it soon, he never will!!
