Well, you can try, but be warned that your writing ability isn't very advanced. No matter how good the story line, or how flawless your grammar, the basic point is that unless you have a Bachelor's in English the techniques that make a story something to be published will not be there. Sorry
I'm 13, and I love to write, but I know that if I published or tried to publish a book, it would be considered a kid's book, and with my story lines that's hardly appropriate. But keep writing, and one day we can both pick up our original ideas and possibly rewrite them and release bestsellers
Be patient! We can both get there eventually.
(Not to mention, if you got an R-rated book published, would your parents approve? Mine wouldn't... )
