Well in my current one, it's about a transgendered male who cross-dresses. I'm not sure if you are familiar with trans lingo, but trans male refers to a boy in a girl body. And well, he enjoys cross-dressing in woman's clothes every now and then, similar to wearing drag.
The main character is seventeen, and he is pre-transition, meaning he hasn't starting hormones or surgery yet. He wants to, but he also wants to stay true to his personality and interests, and he enjoys cross-dressing. Well, not many people take him seriously because of that, so the entire novel is about him trying to make sense of himself and everyone's expectations of him while staying true to who he is.
Bad explanation, but I think that covers the barebones of it.
I'm just worried that a lot of people won't understand this whole "gender" thing and will read it with a very binary view. LIke "well if he enjoys dressing as a woman why doesn't he just stay a girl" kinda thing. Even though gender identity has nothing to do with clothing. It has to do with how you view yourself. Yeah, clothing is an expression of gender identity, but it doesn't define it.
So yeah. >:U
