Interesting article, if a touch over-academic.
As a writer of fanfiction myself, I have come across these types of stories (generally labelled 'slash' fiction) and find them, on the whole, to be unsatisfactory, if only because of the narrrow focus of them.
I specialise in crossover fiction, with stories usually set in universes of my own creation where several 'canons' co-exist. They are mostly adventure stories of one kind or another, but include elements of humour (usually in dialogue) and sometimes romance. As a heteroromantic asexual, I am not disposed to write extended or explicit love scenes, and whilein my early work I rather 'forced' romantic subplots. In my very first such work, a Harry Potter/X-Men story, I shoehorned in romances between Harry Potter and Kitty (Ariel) Pryde, Ginny Weasley and Peter (Colossus) Rasputin, Neville Longbottom and Lavender Brown and a 'bromance' between Snape and Wolverine!
As I progressed, I found it more comfortable to keep the romances more low-key, giving them less space and concentrating on the main plotline and action. I've never written a romantic or erotic tale for its own sake - out of preference rather than prudishness. But the characters do fall in and out of love.
I have written stories featuring Data, and a couple fo them have referred to his particular sexuality. In a Mass Effect/STNG crossover called Of Cats and Dark Energy, Data encounters a female character from the Mass Effect games called Jack. Jack is a young woman who, as a child, was subjected to horrible experiments designed to boost her formidable 'biotic' powers and make her into a super-soldier. Incapable of emotional commitment because she fears vulnerability, she is sexually promiscuous but again unable to lower her guard enough to truly enjoy sex. Intrigued by Datas' 'functionality' she has sex with him and discovers that, because he is no threat to her and makes no demands, she can relax and obtain a fuller enjoyment. But he remains, to her, 'a robot who's good at sex' and a friend. At the end of the story, she urges Data not to hide his light under a bushel, and that his capabilities might be of benefit to other women. I do wonder what can be made of that?
In a much later story, Requiem in Stellaris, Data finds himself in possession of the Infinity Gauntlet at a time of Galactic peril. His 'snap' resets a number of things, but he places himself as the Guardian of Balance. He also revives Tasha Yar as his life-partner because he has "lived tooo long without love". Not sex, love.
Thus my thoughts, as a fanfiction writer, on Lieutenant Commander Data.
