Why are all the colloquialisms associated with being strong male oriented?

I was reading this book about Red Auerbach, legendary coach and general manager of the Boston Celtics, who passed away in 2006. He was a liberal, a Democrat, and a man ahead of his time when it came to race. He was the first NBA coach to start five black players in 1964 and the first to hire a head black coach when he hired Bill Russell in 1966...

He was friends of Democratic presidents from Kennedy to Clinton. He even did some work for Al Gore in 00 because of their shared St. Albans ties.

He passed away in 2006.

Any way...He was giving a speech to Secret Service Agents and he said "it takes balls to do what you do." The assistant director of the Secret Service who was female turned to the author of the book, John Fierstein, and said "now I know what I want for Christmas."

Which gets me to my point. These are the colloquialisms or euphemisms bandied about for strong;

Balls
Brass ones
A set
Cojones

Women are strong too!!!


We need some cool colloquialisms for them.
