It's a fine line between sharing and cheating. Some people like the safer side, some like the hardcore, and some like the middle ground. My patrons usually have preferred middle ground to hardcore in the past.
I can see that - and I understand the appeal - that's an element of why I suggested ntr themes as a subset of sharing earlier - you can definitely make hot scenes where things start as completely consensual, but then they go further [than the mc was originally comfortable with] - though, when the narrative from the start is the LI does stuff behind his back - there's not much room to creatively branch off from.
I could see ntr fans getting onboard with a scenario where things start as a sharing set up with an affable [other male], then hours later they're still going at it and you have the antagonist become more of an asshole- stuff like "Yeah you might wanna get earplugs if you're going to bed, we've still got a lot of stuff to do."
If the other males are not assholes then you might as well just be playing a harem game where the MC is the only male that exists because there is no fucking point of having them fuck the love interest if they are not asshole who treat you like shit and the love interest like a piece of meat.
This perspective genuinely confuses me- but that's okay everyone's entitled to their preferences. I've just never heard this put to words before; traditionally (and my own view) is very much what Turret expressed above - there are two distinct groups - those that find the swinging/hotwifing stuff appealing, and those that find ntr themes appealing.
It sounds like you're in the latter group - perhaps I'm getting hung up on associating the word "sharing" with the former group, because "sharing" implies some agency, as opposed to "having taken from you". If you want the other guy to be an asshole, then there's not much relevance in him asking for permission, is there?
To me it's a huge turnoff when there's a douchebag because I can't insert myself into the mc's shoes in that situation. My opinion alone is there's nothing hot about that - it's not 'scandalous' or 'taboo', it's just a girl that hates you and is fucking some other guy, happens everyday to millions of guys.
What IS 'taboo' or the 'forbidden fruit' is the girl who's still aggressively in love with her bf/husband, and at the same time desires fucking other guys in front of him, knowing both she and he enjoys it.
I keep these fantasies mostly in games and havent partaken in the real world, but my understanding is showing up at some swingers party acting like a douchebag trying to 'steal all the women' is the fastest way to get to kicked out (at the very least, you may not be lucky if you're a real jerk).
