Thanks for the cites. So the first article claims that in a book a writer/producer stated that Roddenberry floated the idea of four and possibly three breasts at some early stage and was quickly talked out of it as a horribly stupid idea. The others are a bit more second hand but consistent with that version. Quite a far cry from “was supposed to have three breasts”? More like a “I know we are in brainstorming and that there a no bad ideas in brainstorming but Gene, that is a bad idea!”
Something tells me that would have backfired spectacularly. And not because of the obvious gratuity. Like, does any guy really want to see a girl with four breasts? Really? (not googling.)
I know a lot of guys who are interested in women’s stories. I get that in some circles it’s frowned upon to be a guy who cares about the interiority of women, and I would call that a genuine societal issue, but it definitely does not apply to all guys. My husband, for example, finds that sort of pandering grotesque.
Not googling is a good call.
Sure, sure, that’s what I say, too! 
It’s a whole fetish category, yes. And more than four in some cases.
Not that there’s anything wrong with that!
Hey, I once read a sci Fi story that had a guy with two dicks. Not my thing, but the story was all right. Someone put that out into the world and found an audience. I’ve encountered some weird stuff in science fiction romance. Like spider erotica. Some people want to make it with spiders, I guess. I love spiders, but not in that way.
Science fiction fans are nothing if not open-minded.
OMG what a great example. The producers had no right, absolutely none, to get what they did get, a phenomenal actress who happened to be wearing a catsuit. The show would have been nearly worthless without Jeri Ryan, but I can’t help thinking that a lesser actress might easily have won that role instead.
Philip Jose Farmer once wrote a story where it turned out Satan not only had two dicks, but he still had his halo. Two, in fact. He’d just moved them to another pair of extremities, is all.
Farmer was Like That, sometimes.
Jeri Ryan is also arguably responsible for the presidency of Barrack Obama.
For those who don’t know what you are talking about:
Ah for the days that trying to pressure your wife to have sex with you in front of other people was enough to shock people.
And we are back to Star Trek.
There’s a substantial number of fans of the surprisingly horny RPG Baldur’s Gate 3 who were vocal in their disappointment that this guy wasn’t one of the romance options.
This goes back aways. Like coming up on 2,500 years.
I remember the story, but was it expected back in 2004 that Ryan would defeat Obama?
No.
Ryan was already screwing the pooch. But it nailed the coffin shut.
Not me, but I think men more… and here’s a memory that this thread triggered. Back in the day, my then girlfriend’s father used to watch The Dukes Of Hazzard just for Daisy Duke. Odd, I thought.

Four breasts… are we talking stagecoach or tethrippon?
Still not googling!
Heh, if the thought of three or four breasts bothers someone, they definitely shouldn’t google “Boobipede”. Which is what it sounds like.
Anyway, I note that a three breasted character appeared in Total Recall, and another in one of the Star Trek films. And there’s from the Hitchhiker’s Guide to the Galaxy series there’s “Eccentrica Gallumbits, The Triple-Breasted Whore of Eroticon Six”.
So to answer the OP it seems clear that part of the audience is “science fiction fans”, at least when it comes to odder configurations.
I mean, plenty of animals have more than two breasts, so it seems at least plausible that a humanoid alien might.
I just didn’t expect the thread to take this turn.
