I have begun the process of adding my TG centric works to Kobo, a company founded in 2009 that has become a world leader in eReading. The charm of Kobo is that they publish in a format that allows a person to use any platform. The following is from their website.

There are drawbacks when publishing here. The categories a writer can classify their work under is quite limited. There is no 'Transgender' subcategory. I've written them, but it seems there is not much of an interest at present to change that. Oh well, nothing is perfect, yet.
