Well, luckily I don't think my spouse will go bald as none of his grandfathers or father have. He'll just get a shock of white hair, eventually.
I can do bald, if it's all bald. Can't do 'the ring'. *lol*
But I can say that I will always go for the guy with the hair. I have a good friend who cut his waist length hair up to get a job, and my attraction level went through the floor. He just wasn't as sexy anymore.
I love to play with it, to brush it and stroke it. I don't find men with long hair less masculine, but more masculine because they are so secure in themselves.
I know my spouse looks much better with the long hair. Short hair just makes him look like a little boy.
