To the girls with wavy/curly hair

This may be a really stupid question, but here it goes:

So, I have curly hair, but my curls are really loose & they spiral. They kind of look like the Conair Infinity clampless curling iron curls, but a little more crazy. The thing is, I've only known my hair was really curly for a little over a year. It was pin-straight until I was around twelve, then I had to start using a flat iron daily because it frizzed & waved awkwardly. I thought the only semi-permanent effect flat irons had on my hair was heat damage, but last summer I decided to go heat-free to liven up my hair a bit. Day by day, I started to notice my curls becoming more defined, and eventually, they started looking the way they do now.

I only have a few friends with curly hair, and they all claim that their hair is curly when it is wet. My hair isn't at all. It curls as it dries. Is that even normal? If you have curly hair, please tell me if it's still curly when it's wet. My friend tells me my hair isn't normal, & my curiosity got to me!!!
