I find it interesting that so many people say something to the effect of, "I write xxx. I have always read xxx and so I write xxx.
Maybe the real question with that is, what, between your ears made you always gravitate toward reading this or that? That would go a long way toward understanding the genres in which you write.
For me, I read for escapism. I have anxiety and depression issues, so I love to choose entertainment where I can relax and enjoy an adventure without some of the ugliness of life. I'll also read some gentle contemporary stories, because they make me feel good.
I love stories with magic or some kind of fantasy element, because it feels like anything is possible. I loved cartoons, anime, manga, and animated films, because many of them have some fantasy elements.
I love happy endings, because life is already depressing. It's why the romance genre and most (light-hearted) MG appeals to me.
I like characters who are active and in control of their lives. I feel helpless or powerless in real life, and I had a controlling family, so I enjoy stories in which characters gain power, whether they gained literal super powers or become active in controlling their destinies.
I tend to feel smothered by peer pressure and expectations, so I am drawn to characters who are, or become, free of such restraints. I love free spirit characters as well. I am female, and sometimes I have to deal with teasing about my lack of crushes/boyfriends or lack of sex, so I enjoy reading about female characters who break away from such pressure.
I don't like being forced into doing things, either. (It's why I hate the forced seduction or rape tropes.)
I also know what genres I would probably never write: Epic Fantasies, Horror, and Mystery/Suspense/Thriller. This is because I tend to get stressed by such genres, or I prefer to watch them on TV/film. I already have lots of fears, so I don't need any more horror in my life, lol. (Well, I don't mind a little bit of paranormal/supernatural horror, but I prefer to watch it than read/write it.)
