What is more attractive to you men?

I'm thinkin about cutting my hair. It's long dark dark brown. Is shortish hair better looking or long??? My hair is in the middle of my back maybe a little shorter. I'm thinkin about cutting it shoulder length. Also I want something EDGY and sexy. Maybe putting some color in it. I just want it to be different it's been the same for years and it's boring. Any ideas??? Does anyone know a website that has pictures of sexy hair ideas??? Please help!!
