I think a lot of girls like long hair on a guy, but not in most circumstances. They're thinking of a muscular, bearded, Neanderthal man with chiseled, instead of the more common variety, which are pasty metalhead kids that are either rail-thin or obese.
Yessss lol my first real crush had long hair like that and omg. He was so sexy. After him, I found more and more men with long hair attractive. But still, my first real crush was one of the best looking guys I've ever seen. And he liked me back too.
Damn. Why I gotta be so dumb and not have gone for it? :/
I like shorter hairstyles on guys, especially mine. Some of the longer hairstyles on guys look kind of scruffy, so if you're going to have longer hair then give it some shape, some body and above all keep it clean!
