Right now, your curls are undefined. With what you'll learn by being on nc.com, you should be able to remedy that.
Curl type is relatively unimportant because it's transient--depending on products, technique, weather, etc. Hair properties are how you choose ingredients/products. Here's a link to help you with yours Curly Hair Basics | Live Curly Live Free Once you determine your properties, you can look for others with hair like yours and see what they use. It's a good place to start.
The foundation of great hair is a good haircut. You need to have appropriate layering, especially with longer hair. The weight of your hair pulls the curl out.

I'm not saying your hair is, but I do think there is a hair type not recognized by the system.
I have a lot of Pacific Islander friends who have a very textured hair type, but it isn't curly at all. It's not completely straight, but it's not curly, and it isn't damaged, it's the way their hair is virgin and fresh. Haircrush on youtube often gets called a 4 type, because she has no defined curl pattern and she's black, but she is someone I wouldn't call a 4 because she has almost no shrinkage. It isn't a small non visible curl, it's a non existent curl, if that makes sense. She's almost tightly wavy in some parts and simply textured in others.
I think the curl typing system is there to give you a general idea, rather than to put you into a suffocating box. i think it's supposed to be fun/visual. i agree w/ kathymack that hair is much more complicated than curl pattern... and if you pick products based on properties first you can have great results. it's not that your curl pattern doesn't matter at all in terms of products/styling, it's that a 2 and a 4 with identical properties (porosity, width, density, elasticity) could have great results from the same products (shampoos, conditioners, LIs, gels etc.) even if their hair looks different. That's the point of figuring out properties.
