While I respect the numerological weight of your triples, I'm afraid I must also recognize the 334 posts in the "lesbian cuckquean thread" at >>486
as being somewhat indicative of the popular view. The board subtitle was chosen without consulting anyone, AFAIK, back when the board was made and there was no-one to consult. (Also if you sage your triples it doesn't count.)
Personally, I have for a while thought that the subtitle ought to be changed to "Women Sharing Their Partners", but I didn't think it was worth going to the meta thread and making a fuss about. Now it seems there's going to be some fuss anyway, so I'm saying it.
>Lesbian cuckolding, on the other hand, feels much further in kind from heterosexual cuckqueaning.
>The culture thinks—rightly or wrongly, don't care, just the messenger—of lesbian relationships as having a more "male" and a more "female" partner. So when the "female" partner in a lesbian relationship is unfaithful, usually portrayed as being with a more aggressive third "top" lesbian, we automatically think of the "male" lesbian partner as being cuckolded. Same goes if the third is a man.
I'm sorry anon but many F/F relationships don't work that way and many people recognize that. There's some natural tendency there because someone has to overcome the lesbian sheep syndrome and also division of labor makes the couple life run smoother, but it tends to be a weak and fluid effect compared to trad gender roles. Butch and femme exist
but can be little more than aesthetics, and even on the aesthetic level both do not have to be represented in a relationship. "So which of you is the man and which is the woman" is dialogue straight from the mouths of political cartoon caricatures, for a reason.
>I submit that a situation where the more "female" lesbian partner encouraged the "male" lesbian partner to go and have sex with other girls would feel like lesbian cuckqueaning. However, because we and the culture at large are naughty little gender essentialists, this can't apply to a situation where the third partners are men because then the unfaithful "male" lesbian would be pushed into a female role. (This undertone of being forced into a heterosexual-female role appears a fair bit in "rape me straight" type fantasies recounted by some lesbians, though it's usually filtered through a few other more explicit undertones first.) We could look at how genderqueering affects things, but that would just serve to further prove this point.
>Lesbian cuckqueaning is therefore impossible if a man is involved; the involvement of a man makes it lesbian cuckolding.
This is resolvable without gendering anything. Cuckolding
or just "cucking" is what person C does to person A who wants to have sexual relations with person B or keep person B to themself but is denied that. Those terms apply regardless of who is doing the cucking. A woman who gets
cucked is a "cuckquean", and "cuckqueaning" refers to being
a cuckquean or to the general situation of a woman getting cucked. The only imprecise part is that because "lesbian" and "cuckqueaning" can both be descriptors for an entire situation, "lesbian cuckqueaning" is a valid contraction of two different ideas that can be phrased with greater specificity: lesbians in a cuckqueaning situation or lesbians being cuckqueans, vs.
a cuckqueaning situation that is, considered as a whole, lesbian because only women are involved. Indeed, the thread at >>486
>I gather that lesbians don't like bisexuals very much.
There's a tendency, yea. The "bislut" thing comes from a few angles; a non-exhaustive rundown:
Bi+het men massively outnumber bi+les women. It feels threatening if your partner has literally
ten times your dating pool; having options affects what a person feels entitled to in the dating market, and while it doesn't necessarily lead to cheating it does lower the threshold for what'll make a person leave a relationship. A bisexual woman is likely to have more relationships ("slut") than a lesbian just because of numbers, and that's before you factor in that men take initiative on asking people out far more than women do, which is why the lesbian sheep thing happens even among confirmed-single confirmed-woman-loving women. A bisexual woman who has dated women has also probably kissed and engaged in sexual activities ("slut") with more people than the lesbian, because men are easy and want to do sex stuff and a woman who is dating women is probably not part of some fundie religion telling her to wait for the altar. If a particular lesbian finds men disgusting rather than merely uninteresting then the idea of this can be like finding out that a woman has fucked dogs - more dogs than humans - and knowing that she might go back to dogs after dating humans.
There's sometimes a feeling that a woman with a man is cheating on the abstract concept of lesbianism, disloyal to feminism and womankind. Lesbian culture can have this kind of woowoo undertone to it that mirrors religious fundie purity culture in its way - if you never even tried men, you are a "gold star" lesbian, but otherwise you're "used goods" and forever tainted in some way by tasting the forbidden fruit (or forbidden meat, amirite). Or to put it another way, boys have cooties, even when a battery of STD tests would disagree.
But also, "man residue" colors a bisexual woman's expectations. Despite what radfems might tell you, not all gendered relationship dynamics are unfavorable to the woman. Did her male exes pay for most of their dates? Pump the gasoline every time to spare her from the smell? Catch spiders and kill roaches so she didn't have to? Princess-carry her when she asked? What about libido - if sex is important to this bisexual, are you as skilled, frequent, or passionate a lover as her male exes? It can all breed an entitlement in the bisexual woman which may be conscious or unconscious. Or, you know, some or all of it might just be the lesbian projecting her fears of that on the "bislut", and hanging onto it as a justification for not being the best lesbian girlfriend she could be.
Finally, women don't make semen or even have natural dicks 
so if she just likes dick then that's something you can't ever give her... unless of course... well, some kinks are born of fears and insecurities, now aren't they?
