A few days ago, I was thinking to myself about reason, while in a 'strange' mood, and suddenly thought, is there a reason why some men are 'better hung' then others?

I started to think about if it was to do with competition for the more attractive female, who would have more success of birthing a live child.

I'm not saying that humanity is shallow, and who would prefure to go on looks then personality, but many men do, and all men a shallow to a degree.

Just a thought though.
