When it comes to sexual preference, when it is relevant to the story, my characters are all heterosexual or "cisgendered," as far as they identify themselves as their birth gender. If it's not relevant to the story, it's not mentioned at all. I have not, nor will I ever, include a LGBTQ character just for the sake of "virtue signaling." If I do, it's because it's relevant to the story. Heck, I'm writing science fiction adventure, not romance; if certain characters are hot for each other than it's either relevant to the plot or to explain the driving motivations behind them.
I really appreciate that. I guess I'll come off as a gayzor bigot, but I am sick to death of reading books or, especially, watching TV, and just having gay sex thrown in my face for no plot reason, just so that the book/show can say, "Look how pro-gay we are!" This has been happening a lot in the last couple of years, to the point one might think it's political manipulation.
I have found Netflix original series to be the worst in this regard. Some show that has nothing to do with romance will need to, in the first 15 minutes, show a couple of naked guys going at it, while any hetro romances are only alluded to if they are mentioned at all. I don't care if there is a gay couple, but why do you have to throw their lovemaking in my face for no reason at all? Especially when it is completely unrelatable to anything in the show or to any other relationships in the show? With some of them, it's like, here we have a serious space battle going on, with millions of lives in the balance, and then, "Oh, by the way, here's a clip of couple of guys humping each other, and now, back to our story."
If you want to throw gay couples in the mix with hetero couples, fine, but treat them all equally. The way some media does it now, you would think that 95% of the planet is overtly homosexual, and hetero relationships don't exist at all.
