The MC’s cock size definitely shouldn't be too large, otherwise the game would become unrealistic, especially since we have an NTR path
The same applies to his performance in sex; initially, he shouldn’t be the best. In the vanilla path, we could see him improving over time, but he shouldn’t start out as the best, as that would harm the logic of the story, particularly the NTR element
However, I do agree he shouldn’t be a loser or repulsive
Currently, he is likely average in terms of dick size and performance, and that's great
His personality and behavior are great. There’s nothing wrong with him—I’m completely satisfied with it
The only thing I didn’t really like about the MC was his face, which I mentioned in the review. Maybe a slightly more masculine look would work better—not overly "alpha", just a bit more masculine, But maybe I'm wrong, to be honest, I'm not entirely sure, because the visual contrast between the MC and the other men adds a lot of tension to the Netorare part, and that's fantastic
