I am currently writing a novel with a Russian main character. Part of his backstory and something that comes up frequently is that he is, agaisnt all odds, a homosexual transvestite. I am particularly looking for colloquialy used neutral/positive and negative terms for transgenderism, homosexuality, and transvestism.
So far my search online has been fruitless. Every term I find is too formal or I can't corroborate anywhere else (like the use of the word трап in that context).
I am aware that the country currently has a bad reputation when it comes to these subjects, which is why I hope a question like this doesn't seem tasteless, offensive, or out of place. This is simply the inquiry of a writer working on a novel with heavy linguistic themes attempting to enrich his story.
