I knew a guy in high school whose hair was considerably long, and he also had a beard, and I told him that if I were going to make a movie about Jésus that I would cast him as Jesus. We also called him Fish- literally everyone called him fish, and there were only a few people that knew his real name- so he was Jésus Fish. ....It's especially funny because he was a gay atheist Man, anatomy was great.
Anyway, I have no problems with guys with long hair. It can look really great.
I had long hair for a while. I do say there are some guys who need to remember that long hair requires both shampoo and conditioner, but a man's hair can be just as long, lush, and as beautiful as a woman's.
