Is my naturally curly hair ugly?

Hey everyone! Im a little concerned about what my hair looks like. I know that many many people think curly hair, they think frizz, poof, and unattractive. I am a little worried that while i am keeping my hair how it is, all of my friends and family are buying Chi's and straightening their hair. (which by the way i have straighted my hair and it took two and a half hours to complete. It puffed uo within 30 minutes.) i have tried to copy a few pictures to see what you guys think about my curls? Is it possible to look pretty and attractive with curly hair? Here's the link!
