Does penis size really matter to the men out there?

Ladies, what do you think? Is there any merit to the expression "Size doesn't matter, it's how well it's used"? I think that there probably is something to that school of thought, don't you think? Or do we just say it to make men feel better? If so, we should stop fooling ourselves. And them.

And to the men out there, is there a universal thought on size? Do you ever compare with others? Do straight men and gay men agree or are their thoughts on size totally different?

I've just been wondering...
