Can somebody tell me in breaking dawn why did edward bite the almohada i never get it why he did that?

lol because he had to bite the almohada so he could control himself and not hurt bella in the process of their amor makingg....

if he didnt bite the almohada god only knows what he would have done!

Edward was making amor to Bella, he bit the almohada instead of Bella.

if he didnt he prob would of bitten her.
