Reasonable enough to me, though of course with most literary criticim of the last 40 years a ‘subtext’ can be based on anything at all, even things that that the writer expressly states don’t exist. It certainly doesn’t need to be a major point. Jeez, if we can have people discussing the homosexual subtext of LoTR, which doesn’t exist at all, we can certainly discuss the Lesbian subtext or MR, which at least does exist albeit incidentally.
The description in Jingo suns something like, “rowed by young, muscular, and not very dressed men”. I think he might be bi, because in The Art Of The Discworld it’s definitely suggested that he was involved with Nanny Ogg.
Proves nothing. If Liberace lived on the Discworld, at some point he would have been involved with Nanny Ogg. 
I think any young man, whatever his inclinations, would have to have had a great deal of fortitude to escape Nanny Ogg, back in the day.
This, in my mind, is the most obvious reference to the lesbian relationship.
Which is as it should be, IMO. 
In a related vein, I continue to respect Pratchett’s polite sensibilities when it comes to discussing sexual matters in his novels – e.g., for the most part it’s something that happens “off-scene”, since it’s a private matter. The only time I can recall an explicit sexual encounter in any of the DW novels was from Men-At-Arms, where Angua and Carrot made the Disc move without even bothering to cancel the bread and newspapers.
Well, it moved for Carrot. Nothing was mentioned of Angua doing any howling. 
Yep, Lofty and Tonker are most definitely a couple. It’s made pretty obvious in the following passage, as well as the one** GuanoLad** quoted:
(Is it a sign of my irrevocable geekiness that this the thread that compelled by to renew my membership?)
Dwarves all look alike except the women don’t have beards, that is to say, not much of a beard.
Female dwarves have perfectly good beards, and are quite proud of them, as any dwarf would be, IIRC.
NANNY OGG: Look, I’m old enough to be your mother.
CASANUNDA: I don’t think so. My mother’s 120 years old. And she’s got a better beard than you.
Pepe, a male character in “Unseen Academicals”, is a flamboyant personality who works in the fashion industry. His apparent lover is Madame Sharn, owner of the dwarf fashion house Shatta. The question is, since both male and female dwarves have beards, is Madame Sharn actually physically female, or a physically male dwarf being campy?
There is a good bit of sexuality in Discworld, it’s simply more subtle than that found in many other authors’ works.
Also, from the same book, Professor Bengo Macarona, who was visiting staff at UU from Genua because of ugliness from a divorce proceeding by an angry wife.
That was a great moment for Ridcully:
nitpick: Pterry uses the plural form dwarfs, not dwarves which is - or started out as - a Tolkienism since the Prof was keen to distinguish the Naugrim from the kind of creatures Snow White set up house with.
As far as I’ve noticed, Mr Slant is far too dry and dusty to be interested, and Reg Shoe is too prone to bits dropping off, so we’re not in a position to say what sort of sex life zombies have, if any.
Not a Disc novel, but in his recent novel with Stephen Baxter, The Long Earth, the police officer who befriended the protagonist when he was a young boy is explicitly described as a lesbian.

:p:p:p
If I might gently suggest, sexuality is minor compared with the much larger issues of equality and sociology. We in the late 20th and now 21st century occasionally think about sexual orientation but really its at best a side-bar to the worries of real life.
Terry Pratchett is beyond clever but he can’t tackle every single side issue which ordinary humanity confronts.
Issues of sexuality are “real life” to those who experience inequality as a result of them.
That being said, unfortunately - unlike 6 years ago when this thread was first created - I doubt Pratchett will have very many more opportunities to create works that address any kind of issue, due to his progressing Alzheimer’s disease.
I don’t think it’s really a Relevant Issue to Pterry. Nor should it be. Part of what makes the Discworld so refreshing is that it is usually free of the issues that are buggering up the real world.
