Its kinda simple really, I would suggest you start out joining a group rp that way you have more people to interact with. Most Group rps have a general enough plot that you can just make up a character. If you are new to rping I would try the cats in the curiosity shop one. Even though its already started the plot is simple enough that you can jump in, the only limitation is writing things from the perspective of a cat.

Outside of that a 1x1 tends to be more involved with some one else since it is just you two in an world.

As for literacy it truly varies, I have partners that tend to drop me one-liners and then some that drop paragraphs. You will have to find some one that writes your preferences ( what type of genres you like, characters, sexual preferences, and literacy )
