I have curly hair and think that curly hair is cute on guys. For instance, Seth Rogen is sexy as hell.
I have very curly hair and have had a few girls ask to run their hands through it. Feels good man. It used to just be wavy when I was a kid and then it started to curl up. I always found it unmanageable and my OCD tendencies wished I had straighter hair but my mom always said I'd get girls playing with my hair and mother knows best. Besides I've found that washing without shampoo and only combing it when wet is a good MO, and I've been growing it out.
