sexual selection

The way relationships form between people has always fascinated me - How does science explain attraction? Through my study of Psychology I came to understand this a little better and found it fascinating trying to explain what the science in attraction was from the evolutionary perspective.
These theories remain controversial, but what is more established is that modern men's sexual organ size is disproportionately linked to how good they feel about their whole bodies, including how much they like their own face, and assess overall physical attractiveness. Researchers find almost 50% would prefer to have a bigger penis. Is this some kind of evolutionary competitive hangover?
