A lot of what you say makes sense. But also the assumption that
most "cucks" get into this type of lifestyle because of homoerotic reasons may be biased based on your own sexuality. i tend to believe that there is a higher percentage of perfectly heterosexual males who appreciate sharing their Women with other men for other reasons. But also my assumption may be biased based on my own sexuality. Let's keep it real and just say neither me nor you know the percentages of guys in this kind of lifestyle who are bi/gay and who are not. At least i haven't yet found numbers about that in a legitimate study.
Where i strictly disagree with you is a part of your last sentence. A male eating pussy is per definition a heterosexual practice because it involves a male and a female instead of being a same-sex act! Of course that does not mean it cannot be homosexually motivated. A man who never had any same-sex sexual relation but fantasizes about it is still homosexual (or bisexual). So it is foremost a question of the mindset, and not the act itself. If the fact that another man's ejaculate is inside a Woman's pussy is the motivating factor and major turn-on for a male to eat a creampie from her pussy then we can rightfully call him bisexual.
On the other hand, if the driving factor is simply eating the pussy, it would
in my opinion be ridiculous to call that bi or gay. Let me explain it with another simply and easily understandable example: Most men (and many, perhaps most Women) masturbate at times. Is a man gay for touching a penis (his own, in this case)? Well, as i said before, it's a matter of the mindset. If he is turned on more by the fact that his hand is touching a penis (his own, in this case) than by the physical pleasure his hand provides to the penis then we can rightfully call him gay (or bi). Yet we know many males masturbate to the imagery of Women or sex with a Woman and it would be ridiculous to think of masturbation as a gay act in general!
One of the three leading scientists who have delved into cuckolding and sharing relationships has announced a future study that will look into a possible biological or evolutionary function of the practice of
creampie eating. Sorry that i can't recall who it was but either Ley, Lehmiller or the female sexologist who's name i've forgotten (i think her first name was Susan?) - silly me! If anybody knows who i am talking about, please share! Anyway i am looking forward to the day that study will be published.
i think a first suggestion was that for some couples creampie eating could be part of the "reclaim sex" with "reclaiming" being brought up as a term in an earlier paper. It was described as serving two main functions. First, let me put it in my own words, it is a way to re-confirm consent. It is a physical/sexual way of saying "Hey, you know I gave consent to you having sex with somebody else. By 'reclaiming you' I make sure you understand that consent is still there and I have not changed my mind." It is "taking back" the partner and being intimate like the many times before instead of "disowning" her, so to speak, if that makes sense. Second, it is a way to more actively involve the partner who took on a more passive role during the process of sharing, in case of a voyeuristic setting with the male "just" watching his spouse instead of being involved in, say, a threesome, and thus putting emphasis on the fact that sharing is indeed a "couple thing" instead of just one partner having sex with somebody else. - None of that is in any way a homosexual practice and eating a creampie as part of the "reclaiming" is then nothing more than an act of strengthening the intimate bond of the (primary) heterosexual couple. - At least that's
my understanding of it.
Please, share your own thoughts on that. Thank you.
