I get it, but the specific element of NTR is the feeling of jealousy. It is the feeling in your gut you get when learn the MC is being cheated on. Of course everyone seems to have an opinion on NTR... some people think that if your MC turns a LI down, if that LI then goes off and has some fun with another partner then that's NTR but that is not the original definition of NTR. So my point is, you don't have to automatically be a loser to have your wife/gf cheat on you. You could be fine in the sack, have a decent job, etc but for whatever reason, your wife cheats on you and that feeling of jelousy in your gut is NTR.
Without getting into specifics about what is true NTR and what not, it's interesting that you consider jealousy as the prime factor for you, but also want a more badass male MC. That seems to be going in two different direction. Cheating obviously doesn't only happen when the guy she's with is a loser. There are so many reasons why it can happen, but a real badass, well adjusted, and confident MC who can take decisive action generally won't be overburdened by jealousy. He will kick the bitch to the curb and move on with his life. If you mean jealousy from the player, rather than the character, then that also seems to conflict more with this type of MC anyways, because he can (and often does in the types of games where Chad MC has an optional NTR route) get plenty of pussy elsewhere.
So to answer your question, I would like to see an MC who gets ticked off and maybe does something about it. There is another game, Rise of the Crime Lord, where is the MC is clearly not a loser. He pleases his wife in bed and is good at his job, but his wife can still cheat on him. Jealousy is not dependent on being a loser. Yes, the MC may be a cuck but that does not automatically make him a loser. Jealousy can happen in a variety of ways to a variety of people.
That's a great game. I enjoyed it, but it proves my point. This is a more western approach with a harem/NTR split and various intermediate states. Plus, if I'm remembering things correctly, that game's optional NTR route basically revolves around a failed marriage where they fall out early in the story and they both can go for other people. There is way less jealousy involved in that type of setting.
I understand many people enjoy different types of NTR for whatever reason, and many prefer the western approach with a lot more control over the MC's dispotion and action. But that comes at the cost of lessened NTR impact in the vast majority of cases. It just seemed weird how you focused on jealousy, but seemed to prefer NTR styles that tends to lead to less jealousy.
I wonder what you think about Our Red Strings, because that game has similar mechanics with a dual protagonist, but manages to keep the NTR vibes strong and spicy.
In this game, the player has 1 choice... that's it. He can tell his wife that one should throw all their values aside or never throw them aside. If the MC says never throw them aside, the game ends. I mean, what is the point of that? That is not really a choice from a player perspective. So basically, you have to play the MC as a loser who is willing to sell his soul to survive or his wife dies. That's just silly.
I think you are being overly harsh on this MC. I mean, he ain't a super stud in bed, but he is hardly a loser as you are so quick to lable him. Of course, this being an unavoidable and focused NTR story, he will get screwed and probably won't be able to put up much of a fight, but he isn't a hopeless loser at this stage of the story. He has a good job, good morals and sense of justice, good background, was a bit spoiled but became a better person after overcoming his hardship during childhood. When asked hypothetically if one would sacrifice their dignity to save their loved one's life, most people would say yes. A parent would do basically anything to save their child, for example. He didn't know the actual reason Clara asked that question, so he answered like most people would.
And finally, when we come back to the topic of "loser" MC in a lot of NTR stories, it's basically to create the foil between the MC and the antagonist. On one side, we have the kind hearted, supportive, good guy MC who fulfills all the requirements of a good partner except being average in bed. Then we have the antagonist who is clearly a shitty person, but he awakens her "female instincts." And the asshole wins out, because NTR. And in the process, we witness the degrading morals and shifting priority of the woman.
To me, normal dudes who lose to some sex god antagonist because he didn't know about the corruption arc happening is not a loser. Personally, I think true cuckold MCs who know exactly what's happening throughout the whole process but doesn't do shit about it are the actual losers.
