Can somebody please explain why does height matters so much even if it is just by a inch or two?

I did not read the whole thing but as a women there is just somethen about height that we have to just have a tall man...of course not all women are like this but i suppose its the part of us that want a big man to protect us and to be able to stand up to another man. It is quite weird to see our boyfriends stand up to another man and your boyfriend just looking so small and worrying about him getting his behind kicked. Also it seems like tall women are not so picky when it comes to height because they are use to being shorter next to their partner most of the time. This is the best answer i can give you, its all about "Does my BF look big and intimidating?".
