There's NOTHING wrong with curly hair. At least, not from most guys' perpective. I think girls don't like it as much because it can be a little harder to work with and change styles sometimes, but guys don't really care about that stuff.
Remember: guys like VARIATION. We like the things that are different from one girl to the next. If everyone looked the same, it would be boring.
I like it but it could be cut to be a bit shorter. Really depends on the guys cause some like straight hair while others like curly hair. Unless you can change it up where it's curly one day and straight the next day.
