>It surprised me too, but I can't say I do not know anyone that did not sign a pre-nup, even one of my best friends from high school did it.

Speaking only for myself, I'd never sign a prenup whether if favoured me or not. I guess I'm a bit old fashioned, but I just can't see myself saying to a woman, "I love you. I want to spend my life with you. Please sign this because I'm not sure I really trust you." And anyone who implied the same to me would see me walking away - quick.
