The Perfect Phallus

I came across The Perfect Phallus last week and have spent some time admiring the cocks on view. But it got me wondering today - is there such a thing as a perfect cock? A few years ago a guy told me when I was at Chariots that he thought my cock was perfect (he was taking a break from giving me amazing head) and I've certainly had many favourable comments before and since then. But would I say it was perfect in their own individual way? Each cock I see is different - maybe they are all perfect? What do you think?
